To a stirred solution of 1,1-dimethylethyl-[2-(2-chloro-1H-pyrrol-1-ylamino)-2-oxoethyl]carbamate (3.1 g) in EtOAc (20 ml) and ether (20 ml) was added ethereal HCl (excess) at room temperature. The reaction mixture was allowed to stir for 19 hours at which time the precipitated product was faltered and washed with EtOAc. Recrystallization from ethanol/ether afforded 0.75 g of the product as a solid, m.p. 220° C. (dec.).
