Procedure

4-(Trifluoromethyl) acetophenone (4.97 g, 26.4 mmol), paraformaldehyde (1.586 g, 2 eq.) and dimethylamine hydrochloride (3.231 g, 1.5 eq.) were mixed together in 7 ml of EtOH, treated with 0.08 ml of 37% HCl, and heated to reflux for 5 h. Cooling down to ambient temperature, filtration and washing with tiny amounts of cold EtOH delivered 4.59 g of the title compound as white crystals, mp. 128–42° C. (dec.).
