Procedure

A mixture of 2.00 g of m-cresol and N2 -(6, 7-dimethoxy-2-naphthylsulfonyl)-L-arginyl-N-(2-methoxyethyl)glycyl chloride hydrochloride obtained above was heated at 90° C for 50 minutes. At the end of this period, the reaction mixture was cooled, washed several times with dry ethyl ether, and then dissolved in 10 ml of dry ethyl alcohol. Addition of cold dry ethyl ether resulted in a precipitate which was washed several times with dry ethyl ether to give 2.12 g (86 percent) of N2 -(6, 7-dimethoxy-2-naphthylsulfonyl)-L-arginyl-N-(2-methoxyethyl)glycine m-tolyl ester hydrochloride in the form of a powder.
