Reaction Steps

To a mixture of 6.0 mL of phosphorus oxychloride and 1.0 mL of dimethylaniline in 20 mL of toluene was added 3.0 g of 5,6,7,8-tetrahydro-2-trifluoromethyl-4-quinazolone. The resulting mixture was refluxed for 3 hours and then cooled to room temperature. The reaction mixture was poured into a ice cold mixture of diethyl ether and water. The organic layer was recovered washed with brine, dried over anhydrous magnesium sulfate, filtered and evaporated to yield the product as a brown solid (3.46 g).
