(3S,8S)-3-(4-Cyclohexylmethoxy-phenyl)-8-{(S)-2-[4-(2,3-dimethyl-pyridin-4-yl)-phenyl]-1-methoxycarbonyl-ethylcarbamoyl}-2,3,8,9-tetrahydro-6H-[1,4]dioxino[2,3-g]isoquinoline-7-carboxylic acid tert-butyl ester (86 mg) was dissolved in 3 mL DCM and 3 mL 4 N HCl (dioxane) was added. The mixture stirred at room temperature for 3 hours, and the mixture was concentrated. DCM was added and the mixture was again concentrated. The solid was triturated with diethyl ether and dried under vacuum to provide (S)-2-{[(3S,8S)-3-(4-cyclohexylmethoxy-phenyl)-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 (71 mg). LCMS: (m/z) 691.
