Procedure

(Step 3) To a solution (2 ml) of methyl (2-{[(t-butoxycarbonyl)amino]methyl}-4-chlorophenyl)carbamate obtained in Step 2 (1.25 g) in ethanol was added 4N hydrogen chloride-ethyl acetate solution (2 ml) at room temperature, and the mixture was stirred overnight. The resulting crystals were collected by filtration, and recrystallized from ethanol and ethyl acetate to give methyl [2-(aminomethyl)-4-chlorophenyl]carbamate hydrochloride (0.85 g) as a white solid.

Workup

  1. filtrationThe resulting crystals were collected by filtration
  2. customrecrystallized from ethanol and ethyl acetate
