Reaction Steps

Methyl 3-(methylamino)-1H-indazole-5-carboxylate (60.0 mg, 0.29 mmol) was dissolved in 1,4-dioxane (0.5 mL). 3N Aqueous hydrochloric acid (0.3 mL, 0.9 mmol) was added and the reaction was heated to 100° C. for 11.5 hours. The heat was removed and the reaction was left stirring at room temperature overnight. The reaction was concentrated to give the title compound (63 mg, 95%) as a tan solid. +ESI (M+H) 192.1; 1H NMR (400 MHz, CD3OD, δ): 8.61 (d, J=0.78 Hz, 1H), 8.19 (dd, J=8.80, 1.57 Hz, 1H), 7.38 (d, J=8.80 Hz, 1H), 3.02 (s, 3H).
