Participants

Reaction Conditions

Reaction Steps

To 4.3 g (0.03 mole) of 4-chloro-5,6-dimethylpyrimidine were added 3.8 g (0.03 mole) of p-chloroaniline and about 10 ml of ethanol; the mixture wasthen heated at 130° C. for about 3 minutes. The reaction mixture quickly became a solution and then the hydrochloride of the desired compound precipitated as the solution was allowed to cool. The crystals thus obtained were separated and ground to a powder and then made alkalineby the addition of a dilute aqueous solution of sodium hydroxide. The insolubles were collected by filtration, washed with water and dried. The resulting crystals were recrystallised from benzene, to give 4.2 g (yield 60%) of the desired Compound No. 25, in the form of colourless needles melting at 170°-173° C.
