Sodium sulfate decahydrate → HCID 89768198, 화합물

To a mixture of ethyl 4-methyl-2-(trifluoromethyl)pyrimidine-5-carboxylate (122.4 mg) in toluene (5.1 mL) was added diisobutylaluminum hydride (1.0 mol/L in hexane, 1.150 mL) at 0° C. The mixture was stirred at 0° C. under nitrogen atmosphere for 2.5 h, and then at room temperature for 2 h. To the mixture was added diisobutylaluminum hydride (1.0 mol/L in hexane, 0.58 mL) again at 0° C. and the mixture was stirred at 0° C. for 2 h. To the mixture was added sodium sulfate decahydrate (556 mg), and the mixture was stirred at room temperature overnight. The mixture was filtered through on the pad of Celite®. The filtrate was concentrated in vacuo to give the title compound (97.6 mg).
