Butyryl chloride → (+)-2-(4-(3-Butyryloxy-1-butenyl)phenyl)-5-decyloxy-pyrimidine

Participants

Reaction Steps

1.0 g of (-)-2-(4-(3-hydroxy-1-butenyl)phenyl)-5-decyloxypyrimidine was dissolved in 20 ml of pyridine, added with 0.5 g of butyryl chloride and stirred at 25°-30° C. for 4 hours. The reaction mixture was diluted with 100 ml of toluene and washed with 4N hydrochloric acid, water, a 5% sodium bicarbonate solution and water successively in that order. The toluene layer was concentrated under reduced pressure and the residue was purified by silica gel column chromatography using toluene/ethyl acetate as eluent to obtain 1.05 g of (+)-2-(4-(3-butyryloxy-1-butenyl)phenyl)-5-decyloxy-pyrimidine.
