Procedure
Nicotinic chloride (1.78 g, 10 mmoL) was added to phenol (1.29 g, 12 mmoL) in 10 mL of tetrahydrofuran (THF). Triethylamine (5 mL) and pyridine (5 mL) were then added to the mixture, which was then stirred at room temperature overnight. After THF was evaporated, the mixture was washed with ethyl acetate in water for three times. The ethyl acetate (EtOAC) layer was then purified with silica column (Hexane: EtOAC=4:1) to give pure product. 1H NMR (400 MHz, CDCl3): δ=9.40 (s, 1H), 8.86 (d, 1H), 8.46 (d, 1H), 7.45 (m, 3H), 7.32 (d, 1H), 7.24 (m, 2H). 2′,3′,5′-Triacetyl ethyl nicotinate riboside (2):
