Stage #1: 1-(tetrahydro-2H-pyran-2-yl)-1H-pyrazole With TurboGrignard; diisopropylamine In tetrahydrofuran at 19 - 27℃; Stage #2: With 1,2-dibromo-1,1,2,2-tetrachloroethane In tetrahydrofuran at 5 - 10℃; for 0.5h; | 3; 4 Example 3. Halogenation. 5 mL of zPr2NH and 120 mL of 1.3 M zPrMgCl/LiCl in THF was added to a solution of 19.4 g of l-(tetrahydro-2H-pyran-2-yl)-lH-pyrazole in 225 mL THF over 1 hour at room temperature. The temperature was maintained at a temperature from 19 °C to 27 °C during addition. The resulting mixture was stirred overnight at room temperature. After cooling to 5 °C, a solution of 1,2-dibromotetrachloroethane (51 g in 100 mL THF) was added over 30 min, during which the temperature was maintained below 10 °C. After warming to room temperature, saturated NH4CI (aq) was added. The organic layer was separated and concentrated to afford a dark oil comprising 5-bromo-l-(tetrahydro-2H-pyran-2-yl)-lH-pyrazole and 3-bromo-l- (tetrahydro-2H-pyran-2-yl)-lH-pyrazole. |
