42% With lithium hydride; In N,N-dimethyl-formamide; Example 33 2-Ethyl-5-phenyl-2H-pyrazole-3-carboxylic Acid Ethyl Ester To a 0° C. mixture of the above-prepared <strong>[13599-12-7]5-phenyl-2H-pyrazole-3-carboxylic acid ethyl ester</strong> (350 mg, 1.62 mmoles) and iodoethane (260 muL, 3.23 mmoles) in DMF (3 mL) was added neat LiH (spatula tip, excess) under a nitrogen atmosphere. The resulting mixture was warmed up to room temperature and stirred overnight. The crude reaction was cooled to 0° C., quenched with aqueous NH4Cl, diluted with ethyl acetate and enough water to dissolve all solids. The phases were separated, and the organic phase was washed sequentially with water and brine, dried over Na2SO4, filtered, and concentrated in vacuo. The regioisomeric products separated and purified by flash chromatography (silica gel, hexanes/ethyl acetate gradient) to give the title compound (167 mg, 42percent yield, higher Rf in hexanes/ethyl acetate) and the undesired regioisomer (175 mg, 44percent yield) as white solids. 1H NMR (CDCl3, 400 MHz): 7.81 (d, 2H); 7.40 (dd, 2H); 7.29 (dd, 1H); 7.13 (s, 1H); 4.63 (q, 2H); 4.37 (q, 2H); 1.47 (t, 3H); 1.41 (t, 3H).

The ethyl acetate layer was washed with water and saturated brine, dried (MgSCU) / and concentrated. The residue was crystallized from ethyl acetate- hexane to give ethyl 1- (2, 4-dichlorobenzyl) -3-phenyl-lH- pyrazole-5-carboxylate (61.0 g, yield: 50percent) as brown crystals, melting point 104-1070C.

Acetic acid' (119 ml) and hydrazine monohydrate (45.8 g) were added to the reaction mixture, and the mixture was stirred with heating under reflux for 2 hr. After cooling to room temperature,' the reaction mixture was concentrated, and the residue was partitioned between water and ethyl acetate. The ethyl acetate layer was washed with saturated aqueous sodium carbonate solution and saturated brine, dried (MgSCM / and concentrated. The residue was crystallized from diisopropyl ether to give ethyl 3-phenyl-lH-pyrazole-5-carboxylate (145 g, yield: 81percent) as a brown solid.1H-NMR (300 MHz, CDCl3) delta: 1-36 (3 H, t, J = 7.2 Hz), 4.36 (2 H, q, J = 7.2 Hz), 7.10 (1 H, s) , 7.30 - 7.46 (3 H, m) , 7.71 - 7.80 (2 H, m) , 11.86 (1 H, brs) .

The mixture was stirred at O0C for 10 minutes and stirred at room temperature for 40 minutes. After the reaction mixture was re-cooled to O0C, 2,2,2- trifluoro-methanesulfonic acid 2,2,2-trifluoro-ethyl ester (500 mg, 2.39 mmol) was added dropwise. The mixture was warmed up to room temperature and stirred overnight. The reaction was quenched carefully with ice water and neutralized with IN aqueous <n="58"/>hydrochloric acid. The mixture was extracted with methylene chloride and the organic layer was dried over sodium sulfate. Filtration and concentration gave a crude which was purified by silica gel chromatography (Isco 12O g column, 10percent ethyl acetate/hexanes) to give 5-phenyl-2-(2,2,2-trifluoro-ethyl)-2H-pyrazole-3-carboxylic acid ethyl ester (360 mg, 52percent) as a white solid.
