Reaction Steps

A mixture of 21.7 g 3-bromo-pyrazine-2-carboxylic acid methyl ester and 25.5 g 4-chloroaniline in 150 ml ethyl acetate is boiled 4 days at reflux. The solution is washed with 4 N hydrochloric acid, water and then with 2 N sodium carbonate. The organic phase is dried over sodium sulphate and evaporated to give the heading compound (recrystallised from isopropanol) m.p. 135°-136°.
