Procedure

To a solution of 4.10 g of Compound (22) obtained in the step (a) in 5 ml of methylene chloride was added 2.5 ml of trifluoroacetic acid under ice-cooling and the reaction mixture was stirred for 1 hour, then, 4 ml of trifluoroacetic acid was added to the reaction mixture and the stirring was continued for 2 hours. After reaction, the solvent was removed to give 5.82 g of glycyl-L-proline p-nitrobenzyl ester trifluoroacetic acid salt as pale brownish oil.
