Reaction Steps
To a stirred solution of 8 parts of α-(aminomethyl)-3,4-dichlorobenzyl alcohol in 4.5 parts of xylene are added 5.2 parts of 2-(nitramino)-2-imidazoline. The whole is heated in an oil-bath at a temperature of about 160°C. till a clear melt is obtained (about 15 minutes). After cooling to about 60°C., the melt is dissolved in acetone and allowed to crystallize. The precipitated product is filtered off and recrystallized from 20 parts of 4-methyl-2-pentanone, yielding 3,4-dichloro-α-(2-imidazolin-2-ylaminomethyl)benzyl alcohol; m.p. 148°C.
