Reaction Steps

3-(Cyclopentyloxy)-5-hydroxy-N-(1-methyl-1H-pyrazol-3-yl)benzamide (200 mg, 0.67 mmol), 2-(azetidin-1-ylcarbonyl)-5-chloropyrazine (159 mg, 0.80 mmol) and potassium carbonate (184 mg, 1.33 mmol) were dissolved/suspended in acetonitrile (3.5 mL). The reaction mixture was heated for 4 hours at 120° C. in a microwave reactor. The mixture was cooled, filtered and concentrated in vacuo. The crude product was chromatographed on silica, eluting with 0-5% methanol in DCM, to give the required product as a white foam (282 mg).
