Reaction Steps

A mixture of 6-(2-chloro-ethoxy)-3-(naphthalene-1-sulfonyl)-1-H-indazole (0.075 g, 0.19 mmoles) and methylamine (0.28 mL, 0.56 mmoles) in DMSO (1 mL) was stirred under nitrogen at 100° C. for 4 hours. Mixture was cooled to room temperature, diluted with water, extracted with EtOAc, washed with water (2×), brine (1×), dried over Na2SO4, and concentrated under vacuum. Compound was purified by flash chromatography using as eluent 5% CH3OH/EtOAc. The purified compound was dissolved in methanol, 1M HCl in ether (0.2 mL, 0.2 mmoles) was added, then dried, to afford the title compound as the HCl salt (0.07 g, 0.19 mmoles), MS: (ES+) 381 [M+H]+
