Versuchsvorschrift
Heat a solution of 2-amino-4-(3-trifluoromethyl-pyridin-2-yl)-benzamide (100 mg, 0.356 mmol) in 2-chloro-1,1,1-trimethoxyethane (bp 138° C.) at 130° C. for 4 hours. Concentrate the mixture under reduced pressure to give 2-chloromethyl-7-(3-trifluoromethyl-pyridin-2-yl)-3H-quinazolin-4-one as an oil which crystallizes on standing.
