(R)-4-[2-(Methyl-sulfanyl)pyrimidin-4-yl]-1-(tetra-hydro-furan-3-yl)-1H-pyrazol-5-amine.

ABSTRACT: The title compound, C(12)H(15)N(5)OS, was obtained by reaction of 2-(2-(methyl-thio)pyrimidin-4-yl)-3-oxopropane-nitrile with (tetra-hydro-furan-3-yl)hydrazine dihydro-chloride, and the racemic product was subsequently separated by chiral chromatography (first peak; [α](D) (20) = +51.3°). The chiral center at the substituted atom of the tetra-hydro-furanyl group has an R-configuration. The pyrimidine and pyrazolyl rings are almost coplanar, their mean planes forming a dihedral angle of 6.4 (1)°. One of the H atoms of the amino group participates in an intra-molecular hydrogen bond with the pyrimidine N atom in position 3. The second H atom is involved in an inter-molecular hydrogen bond, which links the mol-ecules into an infinite chain.

Project description:The chiral center at the substituted atom of the tetra-hydro-furanyl ring in the title compound, C(13)H(17)N(5)OS, has an R configuration. The methyl-sulfanylpyrimidine group and the pyrazole ring are almost coplanar [the maximum deviation from this plane is 0.070 (4) Å], the N-Me substituent being displaced from the methyl-sulfanylpyrimidine-pyrazole plane by 0.880 (4) Å. The secondary amine group participates in an intra-molecular hydrogen bond with the pyrimidine N atom in position 3.

Racemic N-methyl-4-[2-(methyl-sulfan-yl)-pyrimidin-4-yl]-1-(tetra-hydro-furan-3-yl)-1H-pyrazol-5-amine.

Project description:The title compound, C(13)H(17)N(5)OS, was obtained by cyclo-addition of 2-[2-(methyl-sulfan-yl)pyrimidin-4-yl]-3-oxo-propane-nitrile with (tetra-hydro-furan-3-yl)hydrazine dihydro-chloride and subsequent N-methyl-ation of 4-[2-(methyl-sulfan-yl)-pyrimidin-4-yl]-1-(tetra-hydro-furan-2-yl)-1H-pyrazol-5-amine with methyl iodide. The two mol-ecules in the asymmetric unit have opposite absolute configurations and are related by a noncrystallographic inversion center. Both feature intra-mol-ecular N-H⋯N hydrogen bonds. The geometry of the mol-ecules is similar to that observed in the structure of a single enanti-omer of the title compound.

Project description:In the title compound, C(13)H(14)N(2)OS, four C atoms of the phenyl ring are disordered over two sets of sites in a 0.60 (3):0.40 (3) ratio. The heterocyclic ring is essentially planar (r.m.s. deviation = 0.017 Å) and forms dihedral angles of 82.0 (2) and 79.3 (3)°, respectively, with the major and minor occupancy components of the phenyl ring. The crystal packing features N-H⋯O hydrogen bonds, which link the mol-ecules into C(6) chains running parallel to the b axis.

The mol-ecules are stacked on top of each other in the direction of the a axis. The crystal packing is further stabilized by weak intra- and inter-molecular C-H⋯O hydrogen bonds. The absolute configuration of the compound is known from the synthesis.
