실험 절차

A suspension of N-[(3-aminophenyl)methyl]-2,2,2-trifluoroacetamide (46 mg, 0.21 mmol) and N-{3-[3-(2-chloro-4-pyrimidinyl)pyrazolo[1,5-a]pyridin-2-yl]phenyl}-2-(2-thienyl)acetamide (75 mg, 0.17 mmol) (see Example 2, Step B) in i-PrOH (3 mL) was acidified with 2 drops of 12 N HCl and heated in a microwave for 15 min. at 180° C. The reaction mixture was then diluted with DCM, washed with saturated aqueous NaHCO3, dried over Na2SO4, and adsorbed onto silica gel. The crude product was purified by column chromatography to generate the title compound in 67% yield. 1H NMR (400 MHz, CDCl3) δ 8.51 (d, J=6.8 Hz, 1H), 8.31 (d, J=9.1 Hz, 1H), 8.22 (d, J=5.2 Hz, 1H), 7.72-7.75 (m, 2H), 7.63 (s, 1H), 7.46 (d, J=8.3 Hz, 1H), 7.26-7.38 (m, 7H), 7.04 (s, 1H), 6.94 (m, 1H), 6.63 (d, J=5.4 Hz, 1H), 4.48 (d, J=5.7 Hz, 2H), 3.96 (s, 2H). ES-LC/MS m/z=628 [M+H]+.
