Reaction Steps

2.09 g of t-butoxycarbonylsarcosylnitroarginylvalyltyrosylisoleucylhistidylprolyldehydroalanine methyl ester is dissolved in 30 ml of dioxane. To this solution is added 60 ml of 1 N lithium hydroxide. The reaction mixture is stirred for three hours, then neutralized with 1 N hydrochloric acid to pH 7. The solvent is removed by vacuum and the residue is dissolved in N,N-dimethylformamide. Ths solution is filtered and the solvent removed by vacuum. The residue is dissolved in dioxane and added to 300 ml of cold rapidly stirring ethyl ether. The precipate is filtered and dried in vacuo to afford t-butoxycarbonylsarcosylnitroarginylvalyltyrosylisoleucylhistidylprolyldehydroalanine.
