92% | With potassium hydroxide; In ethanol; at 20℃; for 3h; | General procedure: To a mixture of 2-(trifluoromethyl) (1 mmol) and aromatic aldehyde (1 mmol) in ethanol (5 mL), was added (4 mmol) of 50 % of potassium hydroxide. Stirred the reaction mass for 2-3 h reaction was monitored by TLC. After completion of the reaction the ethanol was distilled off from the reaction mass, the solid mass poured in to cold water (25 mL) filtered off the product then washed with cold water and the compounds were confirmed by their spectral data. |

73.2% | 3-(trimethylsilyl)propionic acid with (200 mg, 1.41 mmol) was dissolved in dichloromethane (2 ml). Oxalyl chloride thereto (0.127 ml, 1.48 mmol), and stirred for 3 hours at room temperature was added a DMF (1 drop). The compound obtained in Example 137-2 thereto (288 mg, 1.41 mmol), triethylamine (0.216 ml, 1.55 mmol) and stirred overnight at room temperature added. After the reaction was washed with saturated brine by the addition of chloroform. Dried with magnesium sulfate, and the solvent was evaporated. The residue was purified by silica gel column chromatography (SNAP 10 g, hexane / ethyl acetate) to give the title compound (339 mg, 73.2%) as a white solid. |
