Procedure

To a solution of N-(3-(isoquinolin-3-yl)-4-methylphenyl)-5,6,7,8-tetrahydro-2,6-naphthyridin-1-amine (37 mg, 0.1 mmol) in THF (2 mL) is added DIEA (26 mg, 0.2 mmol) and methylsulfonyl chloride (14 mg, 0.12 mmol) subsequently. The reaction mixture is stirred overnight. After removing solvent by rotary evaporation, the residue is purified by HPLC to afford N-(3-(isoquinolin-3-yl)-4-methylphenyl)-6-(methylsulfonyl)-5,6,7,8-tetrahydro-2,6-naphthyridin-1-amine as a white solid. MS m/z 445.2 (M+1); 1H NMR 400 MHz (DMSO-d6) δ 9.34 (s, 1H), 8.11 (d, 1H, J=8.0 Hz), 7.97 (d, 1H, J=7.6 Hz), 7.88-7.85 (m, 3H), 7.76-7.71 (m, 2H), 7.66-7.63 (m, 2H), 7.16 (d, 1H, J=8.4 Hz), 6.57 (d, 1H, J=5.2 Hz), 4.24 (s, 2H), 3.45 (t, 2H, J=6.0 Hz), 2.91 (s, 3H), 2.75 (t, 2H, J=6.0 Hz), 2.26 (s, 3H).
