Procedure

3-Amino-(2S)-[(4′-trifluoromethyl-biphenyl-4-carbonyl)-amino]-propionic acid methyl ester hydrochloride (0.200 g, 0.493 mmol) was subjected to reductive amination as per general procedure E with biphenyl-4-carbaldehyde (0.080 g, 0.444 mmol) and sodium triacetoxyborohydride (0.208 g, 0.986 mmol) to yield the 3-[(biphenyl-4-ylmethyl)-amino]-(2S)-[(4′-trifluoromethyl-biphenyl-4-carbonyl)-amino]-propionic acid methyl ester which was further hydrolyzed as per general procedure C to yield 3-[(biphenyl-4-ylmethyl)-amino]-(2S)-[(4′-trifluoromethyl-biphenyl-4-carbonyl)-amino]-propionic acid (0.190 g, 70%).
