Reaction Steps

A solution of (S)-methyl 2-(1-aminoethyl)-3-(5-fluoropyridin-3-yl)imidazo[1,2-a]pyridine-5-carboxylate (0.151 g, 0.480 mmol), 4-amino-6-chloropyrimidine-5-carbonitrile (0.089 g, 0.576 mmol) and DIEA (0.252 mL, 1.441 mmol) in n-butanol (2.40 mL) was stirred at 110° C. for 2 h. The mixture was loaded onto silica gel and purified by MPLC (eluted with a gradient of 0-7% MeOH in DCM) to afford the methyl 2-((1S)-1-((6-amino-5-cyano-4-pyrimidinyl)amino)ethyl)-3-(5-fluoro-3-pyridinyl)imidazo[1,2-a]pyridine-5-carboxylate as a light yellow solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 1.55 (d, J=6.65 Hz, 3H) 3.33 (s, 3H) 5.41 (quin, J=6.65 Hz, 1H) 7.16 (d, J=7.24 Hz, 1H) 7.23 (br. s., 2H) 7.38-7.50 (m, 2H) 7.75-7.90 (m, 2H) 7.95 (dd, J=8.61, 1.57 Hz, 1H) 8.42 (br. s., 1H) 8.62 (d, J=2.74 Hz, 1H). LC-MS (ESI) m/z 433.1 [M+H]+.
