To a solution of ethyl (3R)-3-t-butyldimethylsilyloxy-2-methylidenebutanoate (130 g) in methanol (1.3 l) was added a solution of 30% methylamine in methanol (63 ml). The resulting mixture was allowed to stir at ambient temperature for 2 days. Evaporation of the solvent gave ethyl (2S,3R)-3-t-butyldimethylsilyloxy-2-(methylaminomethyl)butanoate (150.0 g).
