Tetrahydrofuran → HCID 86014539, compound

Participants

Reaction Steps

2-Dibromomethyl-4-phenoxy-benzoic acid ethyl ester (2.07 g) was dissolved in tetrahydrofuran (40 mL) and water (15 mL). Silver nitrate (2.56 g) was added. The resulting mixture was heated to reflux for 5 h. The precipitate was filtered off and the reaction was diluted with ethyl acetate. The organic layer was separated and the aqueous layer was extracted again with ethyl acetate. The combined ethyl acetate layer was washed with saturated sodium bicarbonate solution, brine, and dried with magnesium sulfate. After concentration, the crude oil was diluted with 20% ethyl acetate in hexanes (100 mL) and filtered through a pad of silica gel. Further rinse was continued twice. The filtrate solution was concentrated to give the title compound 1.13 g as an oil. 1H NMR (200 MHz, CDCl3) δ 10.62 (s, 1H), 7.98 (d, J=8.6 Hz, 1H), 7.42-7.35 (m, 3H), 7.20-7.14 (m, 2H), 7.04 (d, J=8.2, 2H), 4.41 (q, J=7.0 Hz, 2H), 1.41 (t, J=7.0 Hz, 3H).
