Procedure

To a solution of t-butyl 2-[(S)-4-t-butoxycarbonyl-7-(5-(4-propylphenyl)-2-thienyl)-1,1-dioxoperhydro-1,4-thiazepin-7-yl]acetate (10.4 g) in tetrahydrofuran (120 ml) was added conc. hydrochloric acid (30 ml) in tetrahydrofuran (30 ml) under ice-water cooling and the mixture was stirred at ambient temperature for 15 hours. The mixture was basified with saturated sodium bicarbonate solution and extracted with ethyl acetate. The organic layer was separated, washed with brine, dried over magnesium sulfate, and evaporated in vacuo to give t-butyl 2-[(S)-7-(5-(4-propylphenyl)-2-thienyl)-1,1-dioxoperhydro-1,4-thiazepin-7-yl]acetate (8.94 g) as yellow oil.
