Reaction Conditions

Reaction Steps

A solution of (E)-2-amino-6-[2-(1H-indazol-3-yl)vinyl]phenol (0.10 g, 0.40 mmol) obtained in Step 2 in 1,4-dioxane (1.5 mL) was added with 1-methyl-1H-pyrrole-2-carbonyl chloride (63 mg, 0.44 mmol) and stirred at 210° C. for 15 minutes under microwave irradiation. The reaction mixture was added with saturated aqueous sodium hydrogencarbonate solution and the mixture was extracted with ethyl acetate. The organic layer was concentrated under reduced pressure and the obtained residue was purified by silica gel column chromatography (chloroform to chloroform/methanol=90/10) and crystallized from ethanol to obtain Compound 148 (13 mg, 10%).
