Participants

Reaction Steps

To a stirred and cooled (<15° C.) mixture of 134 parts of potassium hydroxide and 940 parts of pyridine were added portion wise 92 parts of 2-nitrobenzenemethanol. Next there were added 132.5 parts of 4-methoxybenzeneacetonitrile and stirring was continued for 4 hours at room temperature. The reaction mixture was diluted with 3000 parts of ice-water and the whole was acidified with 1270 parts of hydrochloric acid. The precipitate was filtered off, stirred overnight in methylbenzene and dried in vacuo at 60° C., yielding 128.8 parts (50.7%) of α-[4-(hydroxyimino)-3-(hydroxymethyl)-2,5-cyclohexadien-1-ylidene]-4-methoxybenzeneacetonitrile (interm. 40).
