Reaction Steps

To a solution of (2RS,3RS)-2-(3,4-methylenedioxyphenyl)-3-cyclohexyl-3-hydroxypropionic acid (100 mg), HCl.H-L-Trp-OMe (136 mg) and HOBT (55 mg) in dimethylformamide (6 ml) was added WSCD (64 mg) under ice-bath cooling. After being stirred overnight at room temperature, the mixture was poured into water (20 ml) and extracted with ethyl acetate (20 ml). The organic layer was washed with 5% hydrochloric acid solution, 1M aqueous sodium bicarbonate solution and brine, dried over magnesium sulfate, and concentrated in vacuo to afford N-[(2RS,3RS)-2-(3,4-methylenedioxyphenyl)-3-cyclohexyl-3-hydroxypropionyl]-L-tryptophane methyl ester (165 mg).
