To a mixture of 3-{[({(1R,2S)-2-[(tert-butoxycarbonyl)amino]cyclopentyl}carbonyl)amino]sulfonyl}propylacetic acid (1.2 g) and methanol (12 ml) was added a 4 M hydrogen chloride/ethyl acetate solution (6.0 ml) under ice-cooling, followed by stirring at room temperature over one night. The reaction mixture was concentrated under reduced pressure to obtain (1R,2S)-2-amino-N-[(3-hydroxypropyl)sulfonyl]cyclopentane carboxamide hydrochloride (1.1 g).
