実験手順

A solution of 2,6-dichloro-4-nitrotoluene (2.0 g 9.7 mmol) in tetrahydrofuran: methanol mixture (20:11 cm3) was added slowly to a vigorously stirred solution of 10-14% aqueous sodium hypochlorite (15 cm3) at 0° C. After 3.75 h at this temperature, the mixture was poured into dilute hydrochloric acid and then extracted with chloroform (30 cm3). The organic extract was dried and evaporated to yield an organge oil which was purified by flash chromatography over silica gel eluting with an ethyl acetate-petroleum ether gradient. The title compound was obtained as a pale orange solid, m.p. 37°-9° C. (1.8 g).
