Aluminium lithium hydride → tert-Butyl 3-(hydroxymethyl)benzyl(methyl)carbamate

Participants

Reaction Steps

Dissolve 3-[(tert-butoxycarbonyl-methyl-amino)-methyl]-benzoic acid methyl ester (1.70 g, 6.1 mmol) in tetrahydrofuran (60 mL) at 0° C. Add a 1M solution of lithium aluminum hydride in tetrahydrofuran (8 mL, 8 mmol) dropwise and stir for 2 hrs. Quench the reaction with water (3 mL), 5N sodium hydroxide solution (3 mL) and more water (9 mL), filter and concentrate. Purify the residue by chromatography (silica gel) eluting with 40-60% ethyl acetate/hexanes to provide the title compound (1.42 g, 93%).
