Procedure
Following the procedure described in Example 43, 0.3 g of isomer B of t-butyl α-[6-(1-ethoxycarbonyl-3-phenylpropylamino)-5-oxo-2-(2-thienyl)perhydro-1,4-thiazepin-4-yl]acetate [obtained as described in Example 49(h)], was de-t-butyrated using trifluoroacetic acid to afford the desired product as a crystalline powder in a yield of 83 mg. The product softened at about 135° C. and melted at 168° C.
