Reaction Steps

6-Cyanoimidazo[1,2-a]pyridine-2-carboxylic acid (0.770 mmol, 0.144 g), HOBt (0.770 mmol, 0.104 g) and DIPEA (1.539 mmol, 0.199 g) were dissolved in DCM (5 ml) and DMF (1 ml). EDCI (0.770 mmol, 0.148 g) was added and the resulting mixture was stirred for 10 min at RT. (S)-4-(1-(2-aminopropyl)-1H-pyrazol-3-yl)-2-chloro-6-fluorobenzonitrile (0.592 mmol, 0.22 g) dissolved in small amount of DCM was added and the reaction mixture was stirred overnight at RT. The mixture was diluted with DCM, washed with 1M Na2CO3 and water. The organic phase was dried, filtered and evaporated. The crude product was purified by trituration from ACN. 0.054 g of the title compound was obtained. 1H-NMR (400 MHz, DMSO-d6): δ 1.15 (d, 3H), 4.31-4.45 (m, 2H), 4.46-4.57 (m, 1H), 7.00 (d, 1H), 7.61-7.66 (m, 1H), 7.72-7.77 (m, 1H), 7.86-7.92 (m, 2H), 7.93-7.96 (m, 1H), 8.35-8.37 (m, 1H), 8.69 (d, 1H), 9.34-9.37 (m, 1H).
