Ethyl Acetate → N-Methyl-N-(2-methyl-3,4,5,6-tetrahydro-2H-[1,4']bipyridinyl-3'-yl)-3,5-bis-trifluoromethyl-benzamide

Participants

Reaction Steps

Methyl-(2-methyl-3,4,5,6-tetrahydro-2H[1,4′]bipyridinyl-3′-yl)-amine trifluoroacetic acid salt was dissolved in CH2Cl2 (2 mL) and treated with DIPEA (100 μL, 0.59 mmol) and 3,5-bis-trifluoromethylbenzoyl chloride (76 mg, 0.28 mmol, CAS RN 1271-19-8). The reaction mixture was loaded directly on a silica gel column and the title product (23 mg, 26% over two steps) was isolated by elution with 66% EtOAc in n-hexane. MS (ESI): m/z=445.9 [M+H]+.
