Participants

Reaction Steps

To a solution of Boc-Phe-OH (2.65 g), N-methylaniline (1.09 g) and HOBT (1.35 g) in DMF (25 ml) was added WSC.HCl (1.92 g) under ice-cooling. The mixture was stirred for 5 hours at room temperature. After evaporation and extraction with ethyl acetate, the organic layer was washed successively with 2% hydrochloric acid, water, 2% sodium hydrogencarbonate, water and saturated sodium chloride solution, and dried over magnesium sulfate. The evaporated residue was subjected to column chromatography on silica gel (100 g) and eluted with a mixture of chloroform and methanol (100:1). The fractions containing the object compound were combined and evaporated to give Boc-Phe-NMePh (2.17 g).
