Procedure
tert-Butyl [2-({1-[1-(6-chloropyridin-2-yl)cyclobutyl]-3,4-dihydroisoquinolin-7-yl}oxy)ethyl]carbamate (300 mg, 0.658 mmol) were dissolved in isopropanole (4 ml). 5N isopropanolic hydrochloric acid (2 ml) was added and the reaction mixture stirred at room temperature for 4 hours. The solvent was evaporated in vacuo and dichloromethane (20 mL) was added. 1N aqueous sodium hydroxide solution was added dropwise until pH 10 was reached. The phases were separated and the aqueous layer was extracted twice with dichloromethane. The combined organich layers were dried (MgSO4) and concentrated in vacuo. The crude product was used for the next step without further purification. Yield: 150 mg (0.422 mmol, 64%).
