Reaction Steps

90% suspension of sodium hydride in oil (37 mg, 1.387 mmol) was washed with n-pentane and suspended in dry dimethylformamide (5 ml). (1-[1-(6-Chloropyridin-2-yl)cyclobutyl]-3,4-dihydroisoquinolin-7-ol (217 mg, 0.69 mmol) dissolved in dimethylformamide (1 ml) was added dropwise. After stirring at room temperature for 1 hour a solution of tert-butyl-2-bromoethylcarbamate (466 mg, 2.08 mmol) in dimethylformamide (2 ml) was added dropwise. The reaction mixture was heated to 40° C. for 4 hours. The reaction mixture was diluted with water (30 ml) and extracted with dichloromethane (3×). The combined organic extracts were washed with brine twice, dried (MgSO4) and concentrated in vacuo. The crude product was used for the next step without further purification.
