실험 절차

A solution of the product of Example 8f (1.54 g, 10.0 mmol) in thionyl chloride (6 mL) was heated to 84° C. overnight in a sealed vessel. The reaction mixture was cooled and then poured into ice-water (100 mL). The organics were extracted with diethyl ether (80 mL×4). The combined organic phase was washed with saturated aqueous sodium bicarbonate (160 mL×2) and brine (160 mL), dried over anhydrous sodium sulfate and concentrated under reduced pressure to give the title compound as a brown oil (1.20 g, Yield: 89%). 1H NMR (400 MHz, CDCl3) δ 2.45 (t, J=7.4 Hz, 2H), 1.96 (s, 3H), 1.80 (t, J=7.4 Hz, 2H), 1.17 (s, 6H) ppm.
