YieldReaction ConditionsOperation in experiment
11%; 66% With pyridine;copper(II) acetate hydrate; at 50℃; A mixture of 4,4,5,5-tetramethyl-2-[2-[3-(trifluoromethyl)benzyl]-1-benzothiophen-7-yl]-1,3,2-dioxaborolane (1.25 g, 3.0 mmol), <strong>[85290-78-4]ethyl 3-methyl-1H-pyrazole-4-carboxylate</strong> (554 mg, 3.6 mmol) and copper(II) acetate hydrate (300 mg, 1.5 mmol) in pyridine (15 mL) was stirred overnight at 50C, and the reaction mixture was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane-ethyl acetate=65:35) to give ethyl 5-methyl-1-[2-[3-(trifluoromethyl)benzyl]-1-benzothiophen-7-yl]-1H-pyrazole-4-carboxylate (150 mg, yield 11%) as brown amorphous and ethyl 3-methyl-1-[2-[3-(trifluoromethyl)benzyl]-1-benzothiophen-7-yl]-1H-pyrazole-4-carboxylate (884 mg, yield 66%) as a colorless solid. ethyl 5-methyl-1-[2-[3-(trifluoromethyl)benzyl]-1-benzothiophen-7-yl]-1H-pyrazole-4-carboxylate (Reference Example 11) 1H-NMR (CDCl3) delta: 1.38 (3 H, t, J = 7.2 Hz), 2.60 (3 H, s), 4.29 (2 H, s), 4.33 (2 H, q, J = 6.9 Hz), 7.06 - 7.08 (1 H, m), 7.35 - 7.68 (7 H, m), 8.44 (1 H, s). ethyl 3-methyl-1-[2-[3-(trifluoromethyl)benzyl]-1-benzothiophen-7-yl]-1H-pyrazole-4-carboxylate (Reference Example 12) 1H-NMR (CDCl3) delta: 1.38 (3 H, t, J = 7.2 Hz), 2.51 (3 H, s), 4.26 (2 H, s), 4.34 (2 H, q, J = 6.9 Hz), 7.10 (1 H, s), 7.23 (1 H, dd, J = 7.6, 1.1 Hz), 7.39 - 7.55 (5 H, m), 7.76 (1 H, dd, J = 8.0, 1.1 Hz), 8.10 (1 H, s).
11%; 66% With pyridine; copper(II) acetate monohydrate; at 50℃; To a solution of 4,4,5,5-tetramethyl-2-(2-(3-(trifluoromethyl)benzyl)-1-benzothiophen-7-yl)-1,3,2-dioxaborolane (4) (1.25 g, 3.0 mmol) and <strong>[85290-78-4]ethyl 3-methyl-1H-pyrazole-4-carboxylate</strong> (554mg, 3.6 mmol) in pyridine (15 mL) was added Cupric acetate,monohydrate (300 mg, 1.5 mmol) at room temperature. The mixturewas stirred at 50 C under a dry atmosphere (CaCl2 tube) overnight.The mixture was quenched with water at room temperatureand extracted with EtOAc. The organic layer was separated,washed with 1 M HCl aq. and brine, dried over MgSO4 and concentratedin vacuo. The residue was purified by column chromatography(silica gel, eluted with 0-35% EtOAc in hexane) to give 20 (884mg, 66%) as colorless crystals and 21 (150 mg, 11%) as a brown oil.Compound 20: 1H NMR (300 MHz, CDCl3) d: 1.38 (3H, t, J = 7.2Hz), 2.51 (3H, s), 4.26 (2H, s), 4.34 (2H, q, J = 6.9 Hz), 7.10 (1H, s),7.23 (1H, dd, J = 7.6, 1.1 Hz), 7.39-7.55 (5H, m), 7.76 (1H, dd, J =8.0, 1.1 Hz), 8.10 (1H, s).Compound 21: 1H NMR (300 MHz, CDCl3) d: 1.38 (3H, t, J = 7.2Hz), 2.60 (3H, s), 4.29 (2H, s), 4.33 (2H, q, J = 6.9 Hz), 7.06-7.08 (1H,m), 7.35-7.68 (7H, m), 8.44 (1H, s).
