실험 절차
A mixture of Example 1A (15.5 g, 0.1 mol), 2-bromothiazole (18.2 g, 0.11 mol) and potassium carbonate (15.2 g, 0.11 mol) in dimethylsulfoxide was heated at 160° C. under nitrogen for six hours. After cooling and treating with water, the aqueous phase was extracted with dichloromethane. The organic layer was washed with brine, dried, and concentrated to give 27.5 g of the crude as a dark brown oil, which was purified on a silica gel (ethyl acetate/hexane 5-35%) to afford 21.5 g of the product as a brown oil (91% yield) 1H NMR (500 MHz, CDCl3) δ ppm 1.32-1.36 (m, 6H) 1.34 (none, 6H) 1.34 (none, 5 H) 4.45-4.57 (m, 1H) 6.76 (d, J=3.91 Hz, 1H) 6.87-6.93 (m, 2H) 7.15-7.20 (m, 2H) 7.21 (d, J=3.91 Hz, 1H). MS (ESI): m/z 236 (M+H).
