Sodium hydride → HCID 58959492, compound

Participants

Reaction Steps

Sodium hydride (24 mg of a 60% dispersion in mineral oil, 0.6 mmol) was added to a solution of 1-benzylpyrrolidin-3-ol (0.1 ml, 0.6 mmol) in dimethylformamide (1 ml), and the resultant mixture was stirred at room temperature for 5 min. Next, 7-chloro-3-(4-chlorophenyl)-2-(2-chlorophenyl)-2H-pyrazolo[4,3-d]pyrimidine 1-2A-1c (50 mg, 0.13 mmol) was added in one portion, and the mixture was stirred for 2 hours. The reaction mixture was diluted with methyl tert-butyl ether and washed with water (3×). The organic phase was dried over anhydrous magnesium sulfate and concentrated. Purification of the residue by flash column chromatography (50% ethyl acetate in hexanes) provided the title compound 7-(1-benzylpyrrolidin-3-yloxy)-3-(4-chlorophenyl)-2-(2-chlorophenyl)-2H-pyrazolo[4,3-d]pyrimidine 7A-1 (21 mg): MS: 516.1 (M+1)+; 1H NMR (400 MHz, CDCl3) δ 8.6 (s, 1H), 7.5 (m, 6H), 7.3 (m, 7H), 5.8 (m, 1H), 3.7 (s, 2H), 3.2 (m, 1H), 2.9 (m, 1H), 2.8 (m, 1H), 2.7 (m, 1H), 2.5 (m, 1H), 2.2 (m, 1H).
