Procedure

70 mg (0.23 mmol) of 1-t-butoxycarbonyl-(2R)-2-[(3-cyanophenoxy)methyl]pyrrolidine was dissolved in a dioxane solution containing 4 N hydrogen chloride and then stirred at room temperature for 3 hours. The solvent was distilled off to obtain the crude de-t-butoxycarbonyl product. 38 mg (0.25 mmol) of 4-cyano-benzoic acid was dissolved in 3 ml of dimethylformamide, and 100 mg (1 mmol) of N-methyl morpholine and 25 mg (0.23 mmol) of ethyl chloroformate were added thereto and stirred at 0° C. for 5 minutes, and the crude de-t-butoxycarbonyl product was added thereto and stirred at room temperature for 2 hours. The reaction solution was treated in an ordinary manner with ethyl acetate as the extractant to obtain the title compound.
