Temperature: 60 °C

Procedure

1-ethoxycarbonylmethoxy-3,8-dithia-cyclopenta[a]indene-2,6-dicarboxylic acid 2-methyl ester (49 mg, 0.13 mmol) and carbonyldiimidazole (25 mg, 0.15 mmol) were dissolved in THF (6 ml). After stirring for 1.5 hr at 60° C., the reaction was cooled to RT. Benzylamine (30 μl, 0.27 mmol, 2.1 equiv) was added and stirred for 3 hr. Removal of solvent followed by column chromatography yielded 9mg (15%) of 6-benzylcarbamoyl-1-ethoxycarbonylmethoxy-3,8-dithia-cyclopenta[a]indene-2-carboxylic acid methyl ester.
