Reaction Steps

To a solution of 6-(5-amino-pyridin-3-yl)-1-methyl-3,4-dihydro-1H-quinolin-2-one (intermediate A-2, 0.02 g, 0.079 mmol) in DCM (0.5 mL) was added triethylamine (0.024 g, 0.237 mmol) followed by ethanesulfonyl chloride (0.01 g, 0.079 mmol) and the reaction mixture was stirred at room temperature for 1 h. The mixture was diluted with DCM, poured into water (5 mL) and the aqueous layer was extracted with DCM (2×20 mL). Combined organics were dried over Na2SO4, filtered and evaporated to dryness. The residue was purified by silica gel flash chromatography eluting with a 0 to 10% MeOH-DCM gradient to give the title compound (0.007 g, 23%) as a brown solid. MS: 346.0 (M+H+).
