Procedure

The product (1.01 g) of Example 156 (3) was dissolved in N-methyl-2-pyrrolidone (6 mL), and 4-cyanobenzyl bromide (0.392 g) and diisopropylethylamine (1.05 mL) were added thereto. The mixture was stirred at 80° C. for 8 hr with heating. 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-[1-(4-nitrophenyl)-4-piperidinyl]amino}-2-pyrrolidinylcarbonyl}-1,3-thiazolidine (0.685 g) as a yellow oil.
