Procedure

(4Z)-6-Iodo-4-{[(6-piperazin-1-ylpyridin-3-yl)amino]methylene}isoquinoline-1,3(2H,4H)-dione (150 mg, 0.315 mmol) is dissolved in N-methylpyrrolidinone (3 mL) and methylene chloride (0.9 mL), followed by addition of sodium triacetoxyborohydride (0.77 mg, 3.63 mmol), acetaldehyde (0.46 mL, 8.14 mmol) and acetic acid (0.47 mL, 8.2 mmol). After stirring at room temperature for 1 h, methylene chloride and saturated sodium bicarbonate solution were added. The organic layer is separated and dried to give 110 mg (69%) of the title compound as a brown solid. MS (ESI) m/z 504.2 (M+H)+1
