Procedure

2-Fluoro-3-trifluoromethylbenzoyl chloride (92 mg, 0.41 mmol, CAS RN 208173-19-7) was added to a solution of methyl-(4-o-tolyl-pyridin-3-yl)-amine (40 mg, 0.20 mmol, example 1, intermediate a) and DIPEA (70 μL, 0.40 mmol) in THF (1 mL). The reaction mixture was stirred overnight, filtered and all volatiles removed. The resulting oil was purified by flash chromatography on silica gel eluting with 33-50% EtOAc in n-hexane to yield the product as a waxy solid (65 mg, 83%). MS (ESI): m/z=470.0 [M+H]+.
