Reaction Steps

(1R*,2R*,4S*)-N1-[(5-Chloroindol-2-yl)carbonyl]-4-ethoxycarbonyl-N2-[(5-methyl-4,5,6,7-tetrahydrothiazolo[5,4-c]pyridin-2-yl)carbonyl]-1,2-cyclohexane-diamine (244 mg) was suspended in a mixed solvent of ethanol (8 ml) and tetrahydrofuran (5 ml), and a 1N aqueous solution (0.9 ml) of sodium hydroxide was added at room temperature to stir the mixture for 12 hours. After adding 1N hydrochloric acid (0.9 ml), the solvent was distilled off under reduced pressure, and the residue was washed with water and ether to obtain the title compound (152 mg) as a colorless solid.
