Reaction Conditions

Reaction Steps

Into a 10000 mL 4-necked, round bottomed flask was placed a solution of (S)-2-(4-methoxybenzylideneamino)propan-1-ol (693 g, 3.59 mol) in CH3OH (7000 mL). sodium borohydride (271.2 g, 7.17 mol) was added in several batches. The reaction mixture was cooled −10° C. After 2 hours at −10° C., the reaction was warmed to room temperature and concentrated under vacuum. The residual solution was diluted with 2000 mL of water and extracted three times with 3000 mL of ethyl acetate. The combined organic layer was dried over MgSO4, filtered, and concentrated under vacuum. The residue was purified by flash chromatography (silica, 1:4 ethyl acetate/petroleum ether) to afford the title compound as a yellow solid.
