Reaction Steps

A solution of tert-butyl 2-[(S)-7-[5-(4-ethylphenyl)-2-thienyl]-1,1-dioxoperhydro-4-propanesulfonyl-1,4-thiazepin-7-yl]acetate (4.70 g) in formic acid (50 ml) was stirred for 2 hours at room temperature. The volatile was removed in vacuo and three evaporation from chloroform (30 ml) afforded 2-[((S)-7-[5-(4-ethylphenyl)-2-thienyl]-1,1-dioxoperhydro-4-propanesulfonyl-1,4-thiazepin-7-yl]acetic acid (4.60 g) as a pale yellow solid.
