Reaction Steps

To a solution of ethoxy[3-(4-fluorophenyl)(1H-indazol-5-yl)]methanimine hydrochloride (200 mg, 0.62 mmol), N-amino-2-(dimethylamino)acetamide (147.5 mg, 0.95 mmol), and molecular sieves in ethanol was added triethylamine (0.25 mL, 1.86 mmol). The reaction was allowed to stir under a nitrogen atmosphere at 75° C. overnight. The reaction was filtered using a fritted funnel and the filtrate was concentrated. This was purified by semi-preprative HPLC. The material was taken up in ethyl acetate and washed with aqueous sodium bicarbonate. This organic layer was dried with magnesium sulfate, filtered and concentrated to yield the title compound (192 mg, 23% yield). 1H NMR (CD3OD) δ 8.7 (s, 1H), 8.0–8.1 (m, 3H), 7.7 (d, 1H), 7.25 (t, 2H), 4.5 (s, 2H), 3.0 (s, 6H), ES-MS (m/z) 337 [M+1]+.
