4-[(2-乙氧基苯甲酰基)氨基]-1-甲基-5-丙基-1H-吡唑-3-甲酰胺 | 4-(2-ethoxybenzoyl)amino-1-methyl-5-propyl-3-pyrazolecarboxamide | 501120-38-3 | C17H22N4O3 | 330.387 |
X-ray crystal structure data for the substituted 5-(2,3-dihydro-7-benzofuryl)-2-methylpyrazolo[ 4,3-d]pyrimidin-7-one (3) reveal that the two bicyclic heteroaryl systems show no coplanarity along their joint C (5) - C (11) axis with an interplanar angle of 9.6°. Nonetheless, the spatial interatomic distance for O(17)-N(6), determined as 2.73 A, allows the formation of a relatively weak intramolecular hydrogen bond between the pyrimidinone N(6)-H and the O(17) lone pair of the dihydrobenzofuryl moiety.
