Acetyl chloride → HCID 178475033, compound

Participants

Reaction Steps

8.4 g (34.7 mmol) of 4-(isoquinolin-6-yloxy)-cyclohexylamine (15) were dissolved in 100 ml of dichloromethane/pyridine (4:1). At 0° C. a solution of 3.27 g (41.6 mmol) of acetyl chloride in 10 ml of dichloromethane was added and the reaction mixture was stirred at room temperature. After 2 h, the solution was diluted with dichloromethane and washed twice with saturated sodium bicarbonate solution. After washing twice with 2 N HCl, the product was transferred to the aqueous phase. The HCl-layers were adjusted to alkaline pH by addition of solid NaOH and extracted three times with dichloromethane. Drying the organic layers with magnesium sulfate and evaporation of the solvent gave 7.69 g of the crude product. After silica gel chromatography 4.48 g of the title compound were isolated. Rt=0.87 min (Method A). Detected mass: 285.2 (M+H+).
