Participants

Reaction Steps

To a solution of 5-cyclopropyl-N-[2-cyclopropyl-1-methyl-1-(2H-tetrazol-5-yl)ethyl]-4-(2,2,2-trifluoroethoxy)pyridine-2-carboxamide (example 150b, 100 mg, 0.244 mmol) in dry DMF (1.2 ml) was added potassium carbonate (43.8 mg, 0.317 mmol). The reaction mixture was stirred at room temperature for 10 minutes followed by addition of iodomethane (30.5 μl, 0.487 mmol). The reaction mixture was then stirred at room temperature overnight. The reaction mixture was diluted with ethyl acetate and extracted with water and brine. The organic phase was dried over sodium sulfate and evaporated down to dryness. The crude material was purified by preparative HPLC to yield the title compound (40 mg, 39%) and also a second by-product as the regioisomer (11 mg, 10.6%). MS (ESI, m/z): 425.5 (M+H+).
