実験手順
A solution of N-(t-butyloxycarbonylaminoethyl)-1-(3,5-diflurobenzyl)-2-mercaptoimidazole-5-carboxamide acid (1.29 g, 3.13 mmole) prepared as above in 98% formic acid (40 ml) was stirred under an argon atmosphere for 3 hours and the solvent was removed under vacuum. The resulting oil was triturated with ether, and the product was filtered and dried to give N-(2-aminoethyl)-1-(3,5-difluorobenzyl)-2-mercaptoimidazole-5-carboxamide, formate, m.p.: 195°-196° C. (0.630 g, 56%).
