Reaction Steps
To a suspension of sodium hydride (1.570 g, 39.2 mmol) in DMF (46 ml) stirred under argon at 0° C. a solution of 2-furanylmethanol (3.5 g, 35.7 mmol) in DMF (4 ml) was added dropwise over 20 minutes. The reaction mixture was stirred at 0° C. for 15 minutes. 3-bromo-1-propyne (4.24 g, 35.7 mmol) 80% in toluene was dropped in 10 minutes at 0° C., then the mixture was left stirring at room temperature overnight. Water was added and then the mixture was extracted with ethyl ether 3 times. The organic phase was dried over sodium sulphate and concentrated under vacuum. The residue was purified by flash chromatography on silica gel (Biotage SP1 instrument), eluting with a gradient cyclohexane/ethyl acetate 95/5 to 85/15. Evaporation afforded the title compound (1.63 g, 35% yield).
