Participants

Reaction Steps

The alcohol (1 g, 3.37 mmol) of Step (a) was dissolved in dichloromethane (25 mL) and added dropwise at room temperature to a solution of phosphorous tribromide (1 g, 3.7 mmol) in dichloromethane (75 mL). The solution was stirred for 16 hours, then concentrated in vacuo. The residue obtained was triturated with hexane and collected by filtration to yield a white solid (1.17 g, 92%). 1H NMR (CDCl3) δ 8.2 (d, 1H), 7.7 (m, 2H), 7.5 (m, 1H), 7.4 (d, 2H), 6.8 (d, 2H), 5.8 (s, 2H), 4.5 (s, 2H), 3.7 (s, 3H) ppm.
