Reaction Steps

A mixture of N-cyclopropyl-4-oxazol-5-yl-N-piperidin-4-yl-benzamide (600 mg), 2-chloro-5-methyl-pyrazine (100 mg), and cesium carbonate (300 mg) in N,N-dimethylformamide (10 mL) is stirred for 3 days at 80° C. After cooling to room temperature ethyl acetate and water are added. The organic phase is separated, washed with water and brine, dried over MgSO4, and concentrated in vacuo. The residue is chromatographed on silica gel (ethyl acetate/methanol 7:3) to give the title compound. LC (method 1): tR=1.08 min; Mass spectrum (ESI+): m/z=404 [M+H]+.
