3-Bromo-1,1,1-Trifluoro-2-Propanol → HCID 87793684, compound

Participants

Reaction Steps

260 mg of N-(4-tert-butyl-benzyl)-2,2,2-trifluoro-acetamide (1 mmol) were dissolved in 10 ml acetonitrile and treated with 169 mg of potassium tert-butylate (1.5 mmol). After 5 min stirring at rt, 0.125 ml of [rac]-3-bromo-1,1,1-trifluoro-propan-2-ol (1.2 mmol) were added and the reaction mixture stirred at 75° C. bath temperature for 22 h. After cooling down to rt, the reaction mixture was concentrated in vacuo, dissolved in EtOAc/water and the phases separated. The organic phase was then washed with brine, dried over magnesium sulfate, filtered and concentrated in vacuo. The residue was purified by column chromatography (90 g silica gel; EtOAc/heptane 1:4) to give 111 mg of N-(4-tert-butyl-benzyl)-2,2,2-trifluoro-N-(3,3,3-trifluoro-2-hydroxy-propyl)-acetamide as a white solid (30%). MS (ISP) 301.2 (M+H)+.
