A mixture of N-tert-butoxycarbonyl L-methionine (30 g.), cyclopentanol (31 g.), DMAP (44 g.), EDC (30 g.) and dichloromethane (200 ml.) was stirred under an inert atmosphere for 16 hours. It was then washed with 1M. aqueous citric acid (200 ml.), saturated sodium carbonate solution (100 ml.) and brine, dried and evaporated to dryness to give N-tert-butoxycarbonyl L-methionine cyclopentyl ester as a gum(36 g.).
