Reaction Steps
To a solution of 1,2,3,4-tetrahydropyridino[2,3-b]pyridine-7-carbaldehyde in dry dichloromethane (32 mL) were added 4° A seives, sodium sulfate and isopropyl amine. The mixture was cooled to 0° C. followed by the addition of acetic acid (300 μL). The resulting mixture was stirred at room temperature under nitrogen for 18 hrs. The mixture was filtered through celite, diluted with ethyl acetate, washed with saturated sodium bicarbonate and brine, dried over sodium sulfate, evaporated concentrated in vacuo and purified by flash chromatography(10% MeOH/CH2Cl2 ). EI-MS m/z 206 (M+H)+.
