Participants

Reaction Steps

A mixture of the compound (0.10 g) obtained in step 1 and 2N hydrogen chloride/2-propanol was stirred at room temperature for 3 days. The mixture was concentrated under reduced pressure, and to the residue were added acetyl chloride (0.016 mL), triethylamine (0.071 mL) and acetonitrile (4.0 mL), and the mixture was stirred at room temperature for 3 hr. The mixture was diluted with ethyl acetate, washed with saturated aqueous sodium hydrogen carbonate solution and saturated brine, dried and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (NH Chromatorex) (solvent gradient; 50→100% ethyl acetate/hexane) to give the title compound (0.041 g, 43%) as a pale-brown powder.
