Reaction Steps

To a stirred solution of [5-(1H-pyrazol-4-yl)-[1,2,4]triazolo[1,5-a]pyridin-2-yl]-[4-(2-pyrrolidin-1-yl-ethoxy)-phenyl]-amine (0.05 g, 0.128 mmol) in dichloromethane (1 ml) was added triethylamine (23 μl, 0.166 mmol) followed by methanesulfonyl chloride (12 μl, 0.154 mmol). The mixture was stirred for 18 hours at room temperature, then filtered and concentrated in vacuo. The product was purified by preparatory HPLC to yield the desired product. RT: 2.41 min, MI: 468, Method: 2; 1H NMR (DMSO, 300 MHz): 9.56 (s, 1H), 9.47 (s, 1H), 8.94 (s, 1H), 8.18 (s, 2H), 7.69-7.54 (m, 3H), 6.93 (d, 2H), 4.06 (t, 2H), 3.72 (s, 3H), 2.92 (t, 2H), 2.67 (s, 4H), 1.74 (s, 4H).
