Potassium sodium tartarate → 3-(tert-Butyl-dimethyl-silanyloxymethyl)-4-chloro-benzylamine

Participants

Reaction Steps

LiAlH4 (4.11 g, 108 mmol) was added in portions to a sol. of 3-(tert-butyl-dimethyl-silanyloxymethyl)-4-chloro-benzaldehyde oxime (13.0 g, 43.4 mmol) in Et2O (433 mL). The mixture was stirred for 1 h at rt. Aq. sat. potassium sodium tartrate (400 mL) was carefully added to the mixture. The mixture was stirred for 3 h, and was extracted with Et2O (3×). The combined org. extracts were dried over MgSO4, filtered, and the solvents were removed under reduced pressure. Drying under high vacuum yielded the crude title compound (12.4 g, quantitative yield) that was used further without purification. LC-MS: tR=0.84 min; ES+: 327.37.
