3,5-Bis(trifluoromethyl)benzyl bromide → HCID 58966545, compound

Participants

Reaction Steps

To a flask charged with (5-Bromo-pyrazin-2-yl)-[2-(2-methyl-1-morpholin-4-yl-propyl)-5-trifluoromethyl-benzyl]-amine (94 mg, 0.198 mmol) was added THF (2 mL) followed by potassium t-butoxide (28 mg, 0.249 mmol). After 4 minutes, 3,5-bis(trifluoromethyl)benzyl bromide (0.05 mL; 0.272 mol) was added. The mixture was stirred at room temperature for 2 hours. The reaction mixture was quenched with water and diluted with ethyl acetate. The mixture was washed with 2N HCl. The aqueous layer was basified with 1N NaOH and extracted with ethyl acetate (2×). The organic layers were combined, dried over anhydrous sodium sulfate, filtered and concentrated. The residue was purified by flash chromatography (silica gel) (eluting with 10-40% ethyl acetate in hexanes) to afford the title compound (111 mg, 0.159 mmol).
