실험 절차

The crude 1-[1-(4-chlorophenyl)cyclobutyl]-3,4-dihydroisoquinolin-7-ol (3.5 g, 11.22 mmol) was added to a suspension of sodium hydride (60% in mineral oil, 471 mg, 11.79 mmol) in dimethylformamide (25 mL). After stirring for 30 min at room temperature 1,3-propanesultone (1.44 g, 11.79 mmol) was added dropwise. The reaction mixture was stirred over night at room temperature. The dimethylformamide was removed in vacuo. The crude product (8.4 g) was used for the next step without further purification.
