Acetyl chloride → HCID 86655679, compound

Participants

Reaction Steps

To a solution of the compound (0.18 g) obtained in Example 81 and triethylamine (0.13 mL) in acetonitrile (6.0 mL) was added acetyl chloride (0.032 mL), and the mixture was stirred at room temperature overnight. The reaction mixture was diluted with ethyl acetate, washed with saturated aqueous sodium hydrogen carbonate solution, dried and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (NH Chromatorex) (solvent gradient; 60→100% ethyl acetate/hexane) and treated with 2N hydrogen chloride/2-propanol to give the title compound (0.15 g, 80%) as a white powder.
