Tetrahydrofuran → Fur-2-ylmethyl 2-hydroxyethyl ether

Participants

Reaction Steps

Combine ethyl 2-fur-2-ylmethoxyaceate (1.2 g, 6.5 mmol) and tetrahydrofuran (10 mL). Cool in an ice-bath. Add dropwise a solution of lithium aluminum hydride (8.0 mL, 1.0 M in THF, 8.0 mmol). After 2 hours, add water (0.3 mL), add 15% sodium hydroxide solution (0.3 mL), and add water (0.9 mL). Stir vigorously. After 15 minutes, filter the reaction mixture and dry the filtrate over Na2SO4, filter, and concentrate in vacuo to give a residue. Chromatograph the residue on silica gel eluting with 2% ethyl acetate/dichloromethane to give fur-2-ylmethyl 2-hydroxyethyl ether: Rf =0.22 (silica gel, 5% acetone/dichloromethane).
