| Conditions | Yield |
| Stage #1: 3-(1-methylethyl)-1-[5-(trifluoromethyl)pyridin-2-yl]-1H-pyrazole-4-carbaldehyde; 2-(1,3-dioxolan-2-yl)ethyl(triphenyl)phosphonium bromide With sodium hydride In DMF (N,N-dimethyl-formamide) at 0 – 70℃; Stage #2: With hydrogen; 5%-palladium/activated carbon In ethanol at 20℃; for 3.5h; Experimental Procedure Reference Example 52 Reference Example 52 To a mixture of2- (1, 3-dioxolan-2- yl) ethyltetraphenylphosphonium bromide (18.95 g) and N, N- dimethylformamide (178 ml) was added sodium hydride (60%, in oil, 1.71 g) at0 C and the mixture was stirred at room temperature for 30 minutes. Then,3-isopropyl-l- [5-(trifluoromethyl)-2-pyridinyl]-lH-pyrazole-4-carbaldehyde (10.09 g) was added and the mixture was stirred at room temperature overnight, and at70 C for 4 hours. The reaction mixture was poured into dilute hydrochloric acid, and extracted with ethyl acetate. The ethyl acetate layer was washed with saturated aqueous sodium chloride solution, dried(MgS04) and concentrated. The residue was subjected to silica gel column chromatography, and a colorless oil was obtained from a fraction eluted with ethyl acetate-hexane (1: 15, volume ratio). A mixture of the obtained oily substance,5% palladium-carbon (1.28 g) and ethanol (174 ml) was stirred at room temperature for 3.5 hours under a hydrogen atmosphere. Palladium-carbon was removed by filtration and the filtrate was concentrated to give2- {4- [3- (1, 3-dioxolan-2-yl)propyl-3-isopropyl-lH-pyrazol-1-yl}-5-(trifluoromethyl) pyridine (12.84 g, yield98%) as a colorless oil. 1H-NMR (CDC13) g : 1.32 (6H, d, J = 7.0 Hz), 1.72-1. 82 (4H, m), 2.46-2. 58 (2H, m), 2.92-3. 10 (1H, m), 3.82-4. 00 (4H, m), 4.88-4. 96 (1H, m), 7.88-7. 98 (1H, m), 8.02 (1H, d, J = 8.4 Hz), 8.27 (1H, s), 8.56-8. 61 (1H, m). | 98% |
