Participants

Reaction Steps

To a stirred solution of 8.8 g (0.022 mol) sodium hydroxide in 500 ml methanol was added 20 g (0.22 mol) acetamidine hydrochloride. After stirring for an additional 1/4 hour, 37.7 g (0.2 mol) alpha-(2,6-dimethylphenylamino)acethydrazide was added. The reaction mixture was heated under reflux for about 18 hours, cooled and filtered. The filtrate was evaporated under a reduced pressure to give a solid residue. The residue was diluted with dichloromethane, filtered, dried over magnesium sulfate and evaporated under reduced pressure to give a solid residue, which was triturated with ethyl ether/petroleum ether and dried to give 34.3 g of the product, m.p. 125°-126° C. The product is tabulated in Table I as Compound No. 2-A.
