実験手順

(3R,8S)-3-[4-(3,4-Dichloro-benzyloxy)-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 (300 mg) was dissolved in 15 mL DCM and 7.5 mL 4N HCl (in dioxane) added. The reaction was stirred at room temperature for 2.5 hours, DCM was added and mixture was concentrated. The solid was suspended in EtOAc-THF (9:1) and washed with a 10% sodium carbonate solution. The organic layer was washed with brine, nd dried over sodium sulfate and concentrated. DCM added and the mixture concentrated to provide 0.2 g of the product. LCMS: m/z 753.
