Procedure

13.6 ml (0.0136 mol) of 1N sodium hydroxide solution are added dropwise at room temperature to a solution of 1.5 g (0.0034 mol) of N-[2-(4-carbomethoxyphenyl)-1-methyl-ethyl]-N-benzyl-2-hydroxy-2-(2-aminothiazol-4-yl)-ethanamine in dioxan/methanol=1:1 within 10 minutes, with stirring. After 1 hour 20 ml of water are added dropwise sufficiently slowly that a solution is always maintained. After 16 hours 13.5 ml (0.0136 mol) of 1N hydrochloric acid are added, and the mixture is extracted with methylene chloride which is dried over sodium sulphate and evaporated to dryness, and the resulting base is purified on a silica gel column using ethyl acetate/methanol=9:1.
