実験手順

A 10 mL round-bottomed flask was charged with methyl 3-(6-(4-methylthiazol-2-ylamino)-5-phenoxypyridin-3-ylthio)propanoate (65 mg, 0.16 mmol), ethyl 4-chloro-5H-pyrrolo[3,4-b]pyridine-6(7H)-carboxylate (55 mg, 0.24 mmol), and DMSO (2 mL). The reaction was bubbled through with nitrogen and potassium 2-methylpropan-2-olate (54 mg, 0.49 mmol) was added and stirred at ambient temperature for 30 minutes. The reaction was poured into saturated aqueous NH4Cl and extracted with EtOAc. The organic layer was dried with sodium sulfate, filtered and concentrated. The residue was purified on silica gel (50% EtOAc in hexanes) to afford a residue that was dissolved in methanol, KOH (xs) and water (0.5 mL) added and heated to 60° C. over the weekend. The reaction was poured into saturated aqueous NH4Cl and extracted with EtOAc. The organic layer was dried with sodium sulfate, filtered and concentrated. The residue was purified on silica gel (100% EtOAc to 20% methanol in CH2Cl2 with 0.2% ammonia) to afford the title compound (29 mg, 33% yield) as a yellow solid after HCl salt formation. 1H NMR (d6-DMSO)S 10.12 (bs, 2H), 8.34 (d, 1H), 8.31 (d, 1H), 7.42 (m, 2H), 7.36 (d, 1H), 7.17 (m, 3H), 6.84 (d, 1H), 6.76 (s, 1H), 4.47 (m, 4H), 2.28 (s, 3H). Mass spectrum (apci) m/z=434.2 (M+H-3HCl).
