7-Chloro-5-(2-ethoxy-phen-yl)-1-methyl-3-propyl-2,6-dihydro-1H-pyrazolo[4,3-d]pyrimidine.

ABSTRACT: In the title compound, C(17)H(21)ClN(4)O, the benzene ring is oriented at dihedral angles of 1.59?(3) and 1.27?(3)° with respect to the pyrimidine and pyrazole rings, while the dihedral angle between the pyrimidine and pyrazole rings is 0.83?(3)°. An intra-molecular N-H?O hydrogen bond results in the formation of a planar (r.m.s. deviation 0.004?Å) six-membered ring.
