Procedure

WSC[1-Ethyl-3-(3-dimethylaminopropyl) carbodimide hydrochloride](33 mg) and ammonia (3N ethanol solution:0.14 ml) were added under ice-cooling to a DMF solution of 9-(1,3-benzodioxole-5yl)-8-methyl-naphtho[1,2-d]-1,3,-dioxole-7-carboxylic acid (50 mg) which was prepared in Reference Example 13. The mixture was stirred at room temperature for 2 hours, and the reaction was stopped with addition of water. The residue was purified with column chromatography (Silica-Gel 5 g, eluent:ethyl acetate-hexane=1:1) and recrystalized from methanol to yield the title compound (23 g).
