Procedure

(3R,8S)-3-[4-(3,4-Dichloro-benzyloxy)-phenyl]-2,3,8,9-tetrahydro-6H-[1,4]dioxino[2,3-g]isoquinoline-7,8-dicarboxylic acid 7-tert-butyl ester (260 mg), (S)-2-amino-3-[4-(2,3-dimethyl-pyridin-4-yl)-phenyl]-propionic acid methyl ester bis hydrochloride (190 mg), EDC (106 mg), and HOBt (78 mg) were suspended in 2 mL DCM and NMM (0.214 mL) added. The resulting mixture stirred at room temperature for 4 hours and loaded directly onto silica. The residue was purified by silica gel flash chromatography (hexanes to 1:1 hexanes/EtOAc to 1:1 hexanes/EtOAc+1% MeOH) to give 320 mg after drying under vacuum. LCMS: m/z 853.
