Procedure

A mixture of (5-phenyl-indol-2-yl)-methanol 45 (0.259 g, 1.16 mmole), (R)-2-isocyanato-3-phenyl-propionic acid methyl ester 5 (0.286 g, 1.39 mmole), in triethylamine (0.37 ml), and THF (10 ml) was heated to 50° C. under a nitrogen atmosphere for 22 hrs. The solvent was evaporated and the residue was purified by chromatography to give about 0.220 g of (R)-2-(5-phenyl-indol-2-ylmethoxycarbonylamino)-3-phenyl-propionic acid methyl ester 46, mp. 142-143° C.
