Procedure

To a solution of 6-[1-(2-amino-ethyl)-1,2,3,4-tetrahydro-[1,7]naphthyridin-5-yl]-1-methyl-3,4-dihydro-1H-quinolin-2-one hydrochloride (example 12, 0.03 g, 0.081 mmol) in DCM (1 mL) were added triethylamine (0.020 g, 0.201 mmol) and ethanesulfonylchloride (0.011 g, 0.089 mmol) and the reaction mixture was stirred at room temperature for 1.5 h. The mixture was diluted with DCM, poured into H2O (5 mL) and extracted with DCM (2×10 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 5% MeOH-DCM gradient to give the title compound (0.01 g, 29%) as a yellow oil. MS: 429.2 (M+H+).
