Reaction Steps

To a solution of 2-amino-5-morpholin-4-ylmethyl-benzamide (0.58 g, 2.4 mmol) and 2-methyl-pyridine-4-carbaldehyde (0.3 g, 2.4 mmol) in N,N-dimethylacetamide (10 mL) were added NaHSO3 (58.5 wt %, 0.48 g, 2.7 mmol) and p-TSA (0.23 g, 1.2 mmol) and the reaction mixture was heated at 115° C. for 16 hours, and the solvent was removed under reduced pressure. The crude compound was purified by column chromatography (silica gel 230-400 mesh; eluting with 4% methanolic ammonia in dichloromethane) to give the title compound as a white solid. Yield: 0.18 g (22%). MP 267-268° C. 1H NMR (400 MHz, DMSO-d6): δ 11.74 (br s, 1H), 8.77 (d, J=5.4 Hz, 1H), 8.29 (s, 1H), 8.07 (s, 1H), 7.94-7.83 (m, 3H), 3.75 (t, J=4.2 Hz, 4H), 3.74 (s, 2H), 2.77 (s, 6H), 2.53-2.46 (m, 4H). MS (ES+) m/z: 337.41 (M+1).
