Reaction Steps

To a stirred solution of 18.2 g (0.26 m) of sodium nitrite in 130 ml of dimethyl sulfoxide is added, in portions, 29.0 g (0.15 m) of 1-bromo-3,3-dimethyl-2-butanone oxime. A mild exotherm results and external cooling is used to keep the temperature below 27° C. Additional solvent is added to maintain stirrability. After 20 hours stirring, the mixture is poured onto ice and water to give a solid which is collected on a filter. The 10 g of solid, m. 115°-120° C, thus obtained is recrystallized from a hot benzene-petroleum ether mixture to give 7 g of white crystals, m. 124°-125° C.
