Reaction Steps

To a stirred and cooled (ice-bath) mixture of 15 parts of 1-(4-nitrophenyl)hydrazine and 160 parts of absolute ethanol were added 13.5 parts of ethyl ethanimidate hydrochloride. After stirring for 3 hours while cooling, the reaction mixture was poured into water. The precipitated product was filtered off, washed with water and dried, yielding 19 parts (85%) of 1-(1-ethoxyethylidene)-2-(4-nitrophenyl)hydrazine; mp. 101.8° C. (int. 18).
