Reaktionsschritte

To a solution of 14.5 g (0.22 mole) of 85% potassium hydroxide in 300 ml of methanol was added in a stream of nitrogen to exclude air 13.4 g (0.22 mole) of nitromethane and 50.0 g (0.2 mole) of 2,6-di-t-butyl-4-methoxymethylphenol. The magenta solution was stirred for one hour at reflux, with exclusion of air. After cooling somewhat, the solution was neutralized with 13 ml of acetic acid and chilled. A thick paste formed which was filtered, washed and dried. The resulting tan powder (48.1 g, mp 152°-154° C) was recrystallized from 500 ml of heptane, after filtering insoluble matter (10.4 g). The yield of tan crystals was 32.3 g, mp 161°-165° C.
