Participants

Reaction Steps

To 0.65 g (1.62 mmol) of methyl (S)-2-amino-3-{3′-[(benzoylmethylamino)methyl]biphenyl-4-yl}propionate, 0.32 g (1.94 mmol) of benzoylacetone, 3 g of molecular sieve 4A are added to 15 ml of methanol. The reaction mixture is refluxed for 14 h and then filtered through Celite. After evaporation of the solvents, the residue is purified by chromatography on a column of silica and eluted with a 7/3 heptane/ethyl acetate mixture. 0.62 g of desired product is isolated with 70% yield.
