Versuchsvorschrift

The product (1.67 g) of Example 63 (1) was dissolved in N-methyl-2-pyrrolidone (12 mL), and 2-bromoethanol (1.42 mL) and diisopropylethylamine (2.09 mL) were added thereto. The mixture was stirred at 80° C. for 2 days. The reaction mixture was added to saturated aqueous sodium hydrogencarbonate solution and the mixture was extracted with ethyl acetate. The extract was dried and the solvent was evaporated under reduced pressure. The residue was purified by silica gel chromatography to give 3-{(2S,4S)-1-tert-butoxycarbonyl-4-[N-(4-cyanophenylmethyl)-N-(2-hydroxyethyl)amino]-2-pyrrolidinylcarbonyl}-1,3-thiazolidine (0.480 g).
