実験手順

To a flask containing 3-(4-(tert-butyldimethylsilyloxy)cyclohex-1-enyl)-2-fluoropyridine (1.5 g, 4.88 mmol) was added anhydrous dichloromethane (48.8 mL) under nitrogen. After cooling to 0° C., hydrogen fluoride-pyridine complex (1.696 mL, 19.51 mmol) was added dropwise. The reaction mixture was warmed to room temperature and stirred until the starting material had been consumed. The reaction mixture was quenched with saturated aqueous sodium bicarbonate and extracted with dichloromethane before drying over magnesium sulfate, filtering, and concentrating to a clear oil under reduced pressure. The material was used without purification.
