Procedure
5-(4-Chlorobenzyloxy)-quinazoline-2,4-diamine (Example 2) (75 mg; 0.25 mmol) is dissolved in 1:1 HOAc: acetic anhydride and heated to 130° C. for 5 hours. After allowing the reaction to room temperature, the solvent is removed under N2 purge. The resulting solid is dissolved in minimal hot ethanol and allowed to cool to room temperature and the resulting crystals are filtered and dried under vacuum overnight to yield 20 milligrams of N-[2-acetylamino-5-(4-chlorobenzyloxy)quinazolin-4-yl]acetamide.
