Reaction Steps
To a solution of 2-[(4-Nitrophenyl)oxy]ethanol (1 g, 5.4 mmol), in toluene (50 mL) was added 3,4-dihydro-2H-pyran (1.5 mL) and APTS (catalytic amount). The reaction was stirred at 60° C. for 3 hours. The dark solution was then concentrated and purified by flash chromatography using DCM/cyclohexane 30/70 as eluent. The title compound was obtained as an oil (1.33 g, 92%). LC: Rt: 3.12 min.
