Procedure

In a nitrogen atmosphere, 630 mg of 3-phenyl-5-trimethylsilanyl-1H-[1,2,3]triazole-2-carboxylic acid which is the compound prepared in the above 2) was dissolved in 5 ml of dichloromethane, 671 mg of 1-hydroxybenzotriazole monohydrate and 907 mg of a water-soluble dichlorohexyl carbodiimide were added thereto, the reaction solution was cooled down to −78° C. and ammonia gas was introduced thereinto followed by stirring for 2 days. Water was added to the reaction solution, the mixture was extracted with ethyl acetate and the ethyl acetate layer washed with a saturated saline solution and dried over sodium sulfate. The solvent was evaporated in vacuo and the residue was separated and purified by a silica gel column chromatography (hexane/ethyl acetate=2/1) to give 550 mg of the title compound as a white solid.
