Procedure
To a solution of N-{5-[3-(2-chloropyrimidin-4-yl)pyrazolo[1,5-a]pyridin-2-yl]-2-methoxyphenyl}-2-(2-thienyl)acetamide (90 mg, 0.19 mmol) in anhydrous i-PrOH (3 mL) was added N2,N2-dimethylindane-2,5-diamine (37 mg, 0.21 mmol) followed by catalytic 12M HCl. After heating for 10 min. in the microwave at 180° C., the reaction was quenched with saturated NaHCO3 (25 mL) and the solvent was removed by rotary evaporation. The aqueous layer was extracted with DCM (25 mL), the organic layer-concentrated, and purified by column chromatography (1-10% MeOH in DCM) to provide the product (27 mg, 24%) as a yellow solid. 1H NMR (400 MHz, CDCl3) δ 2.18 (s, 6H), 2.65-2.71 (m, 2H), 2.88-2.97 (m, 2H), 3.89 (s, 3H), 3.98 (s, 2H), 6.51 (d, 1H, J=5.3 Hz), 6.94-6.96 (m, 2H), 7.02-7.14 (m, 3H), 7.26-7.28 (m, 1H), 7.35-7.43 (m, 3H), 7.63 (s, 1H), 8.20 (d, 1H, J=5.3 Hz), 8.31 (s, 1H), 8.43 (d, 1H, J=8.9 Hz), 8.79 (d, 1H, J=7.0 Hz) 9.38 (s, 1H), 9.45 (s, 1H) ppm.
