実験手順
A dry RBF set up with stirring bar and reflux condenser was charged with 4-(6-methylpyridin-2-yl)phthalazin-1(2H)-one (780 mg, 3.29 mmol) and POCl3 (10.7 ml, 115 mmol). This was stirred under reflux for 18 h. Excess POCl3 was removed under vacuum with an aid of toluene. The residue was cooled to 0° C. and basified with cold 6 N NaOH until pH=9. Occasionally, ice was added to keep the mixture cold to prevent the hydrolysis. Stirring, agitation, and sonication eventually provided a solid material at basic pH. The solids were filtered, washed with ample amount of water and dried under vacuum to afford a white solid. MS Calcd for C14H10ClN3: [M]+=255. Found: [M+H]+=256.
