Hydrochloric Acid → Benzenemethanamine, N-ethyl-4-(trifluoromethyl)-

Participants

Reaction Steps

N-[4-(trifluoromethyl)benzyl]acetamide (3.085 g, 14.204 mmol) was dissolved in THF (100 ml) and was cooled to zero degrees under argon atmosphere. (Methylthio)methane compound with borane (1:1) (2.698 g, 35.511 mmol) was added and the mixture was refluxed over night at RT. HCl (15 ml, 10%) was gently added and was stirred overnight. The solvent was removed by evaporation Diethyl ether (20 ml) was added and the product was extracted to the water phase by K2CO3 (3×15 ml), the water phase was acidified by HCl (10 ml, 10%) and the product was extracted to the organic phase by EtOAc (3×15 ml). The organic phase was dried (MgSO4) and the solvent was removed by evaporation to give 0.809 g of N-[4-(trifluoromethyl)benzyl]ethanamine (yield 28%).
