Reaction Conditions

Reaction Steps

To a solution of crude N-[3-(4-benzyloxy-phenyl)-1,1-bis-hydroxymethyl-propyl]-acetamide in a mixture of tetrahydrofuran, methanol, water (1/2/2) (450 ml/900 ml/900 ml) is added at room temperature lithium hydroxide (32.7 g, 1.36 mol, 8.0 eq). The reaction mixture is stirred at 55° C. for 5 hours, then extracted with AcOEt (500 ml) and washed with brine (2×300 ml), the combined organic layers are then dried with Na2SO4, filtered and concentrated under vacuum. 2-Amino-2-[2-(4-benzyloxy-phenyl)-ethyl]-propane-1,3-diol is isolated after crystallization using AcOEt.
