Procedure
Following the procedure described in Example 43, 0.15 g of isomer B of t-butyl α-[6-(1-butoxycarbonyl-3-phenylpropylamino)-2-(2-furyl)-5-oxoperhydro-1,4-thiazepin-4-yl]acetate (obtained as described in Example 59) was de-t-butyrated using trifluoroacetic acid, to afford 95 mg of the title compound as a powder.
