反応手順
(S)-2-{[(3S,8S)-3-(3′-Chloro-biphenyl-4-yl)-2,3,6,7,8,9-hexahydro-[1,4]dioxino[2,3-g]isoquinoline-8-carbonyl]-amino}-3-[4-(2,3-dimethyl-pyridin-4-yl)-phenyl]-propionic acid methyl ester bis hydrochloride (0.025 g), 2,5-dimethyl-oxazole-4-carboxylic acid (0.010 g), HBTU (0.027 g) in DCM (3.0 mL), DIEA (0.019 g) was added. The reaction mixture was stirred at room temperature for 2.0 hours, poured onto a silica gel column and eluted with 1% MeOH, 1:1 hexanes-EtOAc to provide (S)-2-{[(3S,8S)-3-(3′-Chloro-biphenyl-4-yl)-7-(2,5-dimethyl-oxazole-4-carbonyl)-2,3,6,7,8,9-hexahydro-[1,4]dioxino[2,3-g]isoquinoline-8-carbonyl]-amino}-3-[4-(2,3-dimethyl-pyridin-4-yl)-phenyl]-propionic acid methyl ester (0.0139 g).
