Reaction Steps

To a stirred solution of 26.0 g of NG -nitro-N2 -(tertbutoxycarbonyl)-L-arginyl-N-butylglycine benzyl ester in 50 ml of ethyl acetate was added 80 ml of 10% dry HCl-ethyl acetate at 0° C. After 3 hours, to this solution was added 200 ml of dry ethyl ether to precipitate a viscous oily product. This was filtered and washed with dry ethyl ether to give 20.8 g of NG -nitro-L-arginyl-N-butylglycine benzyl ester hydrochloride as an amorphous solid.
