A mixture of 1-{5-chloro-8-[4-(2-methoxyethyl)piperazin-1-yl]quinolin-7-yl}ethanone (22 mg, 0.063 mmol) and ammonium acetate (48.8 mg, 0.632 mmol) in methanol (0.36 mL) and acetonitrile (0.36 mL) was heated at 65° C. in a sealed tube for 30 minutes. After cooling, sodium cyanoborohydride (7.95 mg, 0.126 mmol) was added to the resultant mixture. The reaction was heated at 65° C. for another 4 hours, then cooled to room temperature, quenched with saturated sodium bicarbonate, and extracted with dichloromethane. The combined extracts were dried over magnesium sulfate and evaporated to dryness (22 mg, 99%). The residue was used directly in the next step. LCMS calculated for C18H26ClN4O(M+H)+: m/z=349.2; found: 349.1.
