158 mg of isomer B of t-butyl α-[6(R)-(1-benzyloxycarbonyl-3-phenylpropylamino)-5-oxo-3(S)-(2-thienyl)perhydro-1,4-thiazepin-4-yl]acetate (prepared as described in Example 25) were treated with trifluoroacetic acid to remove its t-butyl group in the same manner as described in Example 3. The title compound was obtained as an amorphous solid in a yield of 109 mg.
