Reaction Steps

Hydrazine hydrate (3 mL) was added to a solution of N-[(1E)-(dimethylamino)methylidene]-2-methyl-6-(4-morpholinyl)-1-(1-naphthalenylmethyl)-1H-benzimidazole-4-carboxamide (130 mg, 0.29 mmol) in acetic acid (10 mL) and stirred at 130° C. for 30 min. The reaction mixture was cooled to rt and poured into saturated Na2CO3 solution (20 mL). A filtration was performed, and the filter cake was purified by silica gel chromatography eluted with EtOAc to give the product (88 mg, 72%), as a white solid. 1H NMR (300 MHz, DMSO-d6): δ ppm 2.50 (s, 3H), 3.09 (s, 4H), 3.71 (s, 4H), 6.06 (s, 2H), 6.37 (d, 1H, J=7.8 Hz), 7.20 (s, 1H), 7.34 (t, 1H, J=7.8 Hz), 7.54 (s, 1H), 7.61-7.72 (m, 2H,), 7.86 (d, 1H, J=8.4 Hz), 8.02 (d, 1H, J=7.8 Hz), 8.09 (s, 1H), 8.25 (d, 1H, J=8.4 Hz), 13.85 (s, 1H); LC-MS: m/e=425 [M+1]+
