Procedure

A solution 58.0 g of (S)-2-hydroxymethyl-1-pyrrolidine carboxylic acid phenylmethyl ester, 45.0 g of (1,1-dimethylethyl)dimethylsilylchloride, 69 ml of triethylamine, 1.50 g of 4-(dimethylamino)pyridine and 50 ml of methylene chloride is stirred at room temperature for 18 hours. The resulting solution is washed with water, 2N hydrochloric acid, saturated sodium bicarbonate and sodium chloride. The organic layer is dried and concentrated in vacuo. The residue, dissolved in methylene chloride, is filtered through a silica gel pad and concentrated in vacuo to give 76.5 g of the desired product as a colorless oil.
