To a solution of 275 mg (1.00 mmol) of 3-methyl-2-[5-(amino)pentan-1-ylthio]-1,4,7b-triazacyclopent[cd]indene in 30 ml of acetonitrile were added 0.19 ml (1.36 mmol) of triethylamine and 231 mg (1.20 mmol) of pentafluoropropionic acid ethyl ester. The mixture was stirred for 15 hours at room temperature, and the the solvent was distilled off. To the residue was added ethyl acetate, washed with water, and dried over anhydrous magnesium sulfate. The solvent was distilled off, and the residue was purified by column chromatography (eluent: ethyl acetate) to afford 245 mg (58.1%, a pale brown solid) of the desired compound.
