Preparation of N-methyl-4-nitrosoaniline
10 g methylaniline dissolved in 15 ml conc. hydrochloric acid and 40 g ice are treated with 7 g sodium nitrite in 25 ml water. N-Nitroso-N-methylaniline separates as a yellow oil, which solidifies on cooling (m.p. 12°-15° C). 2 g N-Nitroso-N-methylaniline are dissolved in 4 g ether and 8 g absolute alcohol which have been saturated with hydrochloric acid gas then added. After a time needles separate out which are filtered and washed with a mixture of alcohol and ether. Yield almost theoretical, m.p. 118° C.
