6-(4-Chloro-5-trifluoromethyl-pyrimidin-2-ylamino)-3,4-dihydro-1H-quinolin-2-one (50 mg, 0.145 mmol) was added to 0.5 ml NMP and 3-Methanesulfonyl-benzylamine mono hydrochloride salt (32 mg, 0.145 mmoles) and triethylamine (0.060 ml, 0.435 mmoles) were added the reaction was heated to 100° C. for one hour. The reaction was cooled to room temperature and 0.5 mL NMP was added. The reaction was then filtered and purify by preparative reverse phase HPLC 30×50 mm XTerra C18 prep column, fifteen minute gradient 15-60% (0.1% NH4OH in Acetonitrile) and (0.1% NH4OH in water)), flow rate 40 mL/min. The desired product eluted (retention time 8.41 minutes) and was concentrated to a solid (38 mg, 54% yield). 1H NMR (Methanol-d4, 400 MHz) δ 2.52 (m, 2H), 2.80 (m, 2H), 2.99 (s, 3H), 4.80 (s, 2H), 6.73 (d, J=9 Hz; 1H), 7.22 (d, J=9 Hz; 1H), 7.37 (s, 1H), 7.57 (t, J=8 Hz; 1H), 7.64 (d, J=8 Hz;1H), 7.80 (m, 1H), 7.90 (s, 1H), 8.12 (s, 1H). HPLC ret. time: 5.390, LRMS (M+) 492.12.
