To a solution of 1-{6-chloro-4-[trans-4-(hydroxymethyl)cyclohexylamino]-1,5-naphthyridin-3-yl}ethanone (140 mg, 0.42 mmol) in methylene chloride (10 mL) was added triethylamine (0.12 mL, 0.84 mmol) and methanesulfonyl chloride (65 μL, 0.84 mmol) and the reaction mixture was stirred at room temperature for 4 h. The reaction mixture was diluted with satd. aq. sodium bicarbonate, the layers were separated and the organic layer was concentrated to afford the crude product (180 mg) as a yellow solid which was used without further purification: 1H NMR (500 MHz, CDCl3) δ 10.90 (br s, 1H), 8.95 (s, 1H), 8.09 (d, J=8.7 Hz, 1H), 7.53 (d, J=8.7 Hz, 1H), 5.10-4.95 (m, 1H), 4.11 (d, J=6.5 Hz, 2H), 3.03 (s, 3H), 2.68 (s, 3H), 2.39-2.26 (m, 2H), 2.01-1.92 (m, 2H), 1.90-1.78 (m, 1H), 1.47-1.24 (m, 4H); ESI MS m/z 412 [M+H]+
