Reaction Steps
To a solution of 4-{1-perhydro-2H-pyran-2-yl-5-[1-(triphenylmethyl)(1,2,4-triazol-3-yl)]1H-indazol-3-yl}phenylamine (0.300 g, 0.498 mmol) was added tetrahydrofuran (4.50 mL), triethylamine (0.345 mL, 2.48 mmol), and 2-furoyl chloride (0.058 mL, 0.735 mmol). The mixture was stirred for 16 h at ambient temperature and poured into saturated sodium bicarbonate (50 mL). The aqueous layer was extracted with ethyl acetate. The combined organic extracts were washed with saturated sodium bicarbonate, dried over anhydrous sodium sulfate, filtered and evaporated. Purification by preparative HPLC (30-80% acetonitrile/water) followed by washing with saturated sodium bicarbonate and extraction with ethyl acetate gave the title compound (0.0086 g, 5% yield). 1H NMR (DMSO-d6) δ 8.75 (d, 1H), 8.10 (m, 6H), 7.74 (m, 1H), 7.39 (d, 1H), 6.75 (m, 1H). ES-MS (m/z) 371 [M+1]+.
