Versuchsvorschrift

A mixture of 4′-(trifluoromethyl)acetophenone (9.8 g) and N-(1,1-dimethoxyethyl)-N,N-dimethylamine (8.2 g) was heated at 112° C. overnight, under nitrogen. The reaction mixture was cooled and concentrated giving an orange solid. Trituration with diethyl ether gave the title compound as a yellow solid
