Potassium Carbonate → 1-Methyl-α-(trifluoromethyl)-1H-imidazole-5-methanol

Participants

Reaction Steps

According to Reference Example 8-2, by use of 1-methyl-1H-imidazole-5-carbaldehyde (300 mg, 2.72 mmol) dissolved in N,N-dimethylformamide (4.5 mL), potassium carbonate (75 mg, 0.54 mmol) and (trifluoromethyl)trimethylsilane (0.442 mL, 2.99 mmol), the mixture was stirred and reacted at room temperature for 3 hours. Then, purification by preparative thin-layer chromatography (chloroform/methanol=10/1) was performed to give 2,2,2-trifluoro-1-(1-methyl-1H-imidazol-5-yl)ethanol (Compound DK) (358 mg, yield: 73%).
