Versuchsvorschrift

A suspension of 2.00 g of 2-nitrophenol, 1.72 g of 1-chloro-3-methoxypropane and 3.04 g potassium carbonate in 20 ml of N,N-dimethylformamide is stirred at reflux over 23 hours. The reaction mixture is concentrated by evaporation. The residue is partitioned between ethyl acetate and a 9:1 water/brine mixture. The water phase is extracted using ethyl acetate (2×). The organic phases are washed with brine, dried over sodium sulphate and concentrated by evaporation. The title compound is obtained as a yellow oil from the residue by means of flash chromatography (SiO2 60F). Rf=0.33 (1:2 EtOAc-heptane); Rt=4.08.
