Procedure

The title compound is prepared by the procedure of Example 50 using 20.0 g of (R)-2-pyrrolidinemethanol, 44.0 g of benzyl chloroformate and 200 ml of diethyl ether to give 56.4 g of (R)-2-hydroxymethyl-1-pyrrolidine carboxylic acid phenyl methyl ester. Forty-five g of (R)-2-hydroxymethyl-1-pyrrolidine carboxylic acid phenylmethyl ester is reacted with 38.4 g of (1,1-dimethylethyl)dimethylsilylchloride, 58 ml of triethylamine, 1.3 g of 4-(dimethylamino)pyridine and 450 ml of methylene chloride to give 41.5 g of the desired product as a colorless oil.
