Reaction Steps

2-(2-Methoxy-phenyl)-7-trifluoromethyl-3H-quinazolin-4-one 2-(2-Methoxy-benzoylamino)-4-trifluoromethyl-benzamide (3.8 g, 11.24 mmol) was suspended in 145 ml 5% aqueous NaOH solution then refluxed fro three hours at 120° C. The reaction was cooled to room temperature and adjusted to pH 4 causing the desired product to precipitate from solution. Solid was collected by vacuum filtration as a white solid and dried on the lyophilizer for 24 h. White solid 2.7 g, 75% yield. LC/MS (10-99%) M/Z 321.1, retention time 3.25 minutes.
