実験手順

To a stirred mixture of 6-bromo-1-methyl-3-phenyl-4-(trifluoromethyl)-1H-pyrazolo[3,4-b]pyridine (0.15 g, 0.422 mmol) and Na2CO3 (0.135 g, 1.267 mmol) in dry DMF (6.0 mL), glycine methylester×HCl (0.08 g, 0.633 mmol) was added at it and heated to 100° C. for 6 h. The reaction mixture was cooled to it and poured into rapidly stirred ice cold water. The crude compound was extracted with EtOAc and purified by column chromatography (eluent: 10% EtOAc in hexane) to yield the title compound as a colorless solid (0.05 g, 32%). [1H-NMR (CDCl3, 300 MHz) δ 7.55-7.38 (m, 5H), 6.68 (s, 1H), 5.42 (t, 1H), 4.32 (d, 2H), 4.05 (s, 3H), 3.75 (s, 3H); LCMS RtC=0.469 min; [M+H]+=364.8]
