실험 절차

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 (0.306 g, 0. 51 mmol) in tetrahydrofuran (4.5 mL) was added nicotinoyl chloride hydrochloride (0.409 g, 0.79 mmol) and triethylamine (0.35 mL, 2.52 mmol). The reaction mixture was stirred overnight at room temperature, and quenched with methanol (0.20 mL). This mixture was washed with sodium bicarbonate (aqueous) and extracted with ethyl acetate (3×). The organic fractions were combined, dried with magnesium sulfate, filtered, and condensed resulting in a crude solid (0.346 g) that was used without further purification. This solid was dissolved in 6 N hydrochloride solution (aqueous) (5 mL) and 1,4-dioxane (5 mL) and allowed to stir at room temperature overnight. The reaction was quenched by adding the reaction mixture dropwise to a solution of sodium bicarbonate (saturated aqueous) to form a precipitate, which was filtered and dried in a vacuum oven overnight. (0.109 g, 56% yield): 1H NMR (DMSO-d6) δ 9.12 (d, 1H), 8.78 (dd, 1H), 8.72 (s, 1H), 8.34 (dt,1H), 8.29 (s, 1H), 8.04 (m, 5H), 7.68 (d, 1H), 7.60 (ddd, 1H); ES-MS (m/z) 382 [M+1]+.
