Reaction Steps
Sodium borohydride (10 mmol) was added to a suspension of 7-(2-Chloro-6-fluorophenyl)-5-(4-chlorophenyl)-4,7-dihydro-[1,2,4]triazolo[1,5-a]pyrimidine (1 mmol) in methanol (5 mL). The reaction mixture was refluxed for 30 min, then cooled to room temperature, diluted with water (50 mL) and stirred sufficiently. The resulting mixture was filtered and washed with water to give the crude product, which was further purified by recrystallization from a mixture of EtOAc and Hexanes to provide the product as a white solid. Yield: 89%. m.p. 227-228° C. Rf=0.16 (EtOAc/Hexanes 33.3:66.7). MS: MH+=363. 1H NMR (500 MHz, DMSO-d6): δ 7.54-7.15 (m, 8H, CHar), 5.98-5.94 (m, 1H, CH), 4.82-4.78 (m, 1H, CH), 2.47-2.13 (m, 2H, CH2). HPLC: 99.8% (Method A, tR=3.67 min).
