Reaction Conditions:

with orthoformic acid triethyl ester at 23 - 130;Inert atmosphere;

Steps:

1,3-Bis(2,4,6-trimethylphenyl)-4,5-dihydroimidazolium chloride5
A mixture of 1.12 g (3.03 mmol) of N,N'-bis-(2,4,6-trimethylphenylamino)ethane dihydrochloride, 10mL of triethyl orthoformate, and one drop of 96% formic acid was heated in a distillation apparatus until the ethanol distillation ceased. The temperature of the reaction mixture reached 130 ^oC. Uponcooling to 23 ^oC, a colorless solid precipitated which was collected by filtration and dried in vacuo.
