Reaction Steps

4-Trifluormethylbenzamidine hydrochloride (22.4 g, 0.1 mol, from example 41) is added to a solution of potassium methylate (0.22 mol) in anhydrous methyl alcohol (65 mL) and stirred for 15 minutes at ambient temperature. Dimethyl malonate (12.6 mL, 0.11 mol) is added and the mixture is heated to reflux for 4 hours. After cooling, the resulting suspension is diluted with methyl alcohol (50 mL).
