Procedure

A solution of 6-methoxy-4-morpholinoisoquinolin-1-ol (0.33 g, 1.268 mmol) in POCl3 (5 ml) was refluxed for overnight. The solvent was evaporated under reduced pressure and the residue was diluted with cold water. The aqueous solution was basified by solid sodium carbonate and extracted with ethyl acetate. The combine organic layer was dried over anhydrous sodium sulfate, filtered and evaporated under reduced pressure to get crude compound. The crude compound was purified by silica gel chromatography (10% ethyl acetate in pet ether) to get desired compound (0.065 g, 18%) as oil. 1H NMR (400 MHz, DMSO-d6): δ ppm 8.18-8.16 (d, J=8 Hz 1H), 7.94 (s, 1H), 7.45-7.40 (m, 2H), 3.98 (s, 3H), 3.88-3.86 (m, 4H), 3.09-3.07 (m, 4H); MS: MS m/z 279.1 (M++1).
