Reaction Steps

Diethenyl(3-methoxy-4-nitrophenyl)phosphane oxide (0.480 g, 1.94 mmol), ethylamine hydrochloride (0.174 g, 2.12 mmol), and 1 N NaOH (2 mL) were dissolved in 50% aqueous THF (5 mL) and heated to 105° C. under nitrogen. After one hour, another portion of ethylamine was added to the reaction mixture. The reaction mixture was refluxed for an additional 2 h, and then cooled to it. The reaction mixture was partitioned between saturated aqueous NaHCO3 and CH2Cl2. The aqueous phase was washed once with CH2Cl2 and the organic layers were combined. The organic extracts were washed with brine, dried over MgSO4, filtered, and concentrated. The residue was purified by silica gel chromatography (0-10% 7N ammonia in methanol:dichloromethane) to afford the compound (0.267 g, 46% yield).
