Procedure

A mixture of 3-hydroxy-5-{[(1S)-2-hydroxy-1-methylethyl]oxy}-N-(3-methyl-1,2,4-thiadiazol-5-yl)benzamide (237 mg, 0.77 mmol), 5-(azetidin-1-ylcarbonyl)-2-chloropyridine (151 mg, 0.77 mmol) and potassium carbonate (213 mg, 1.54 mmol) in acetonitrile (5 mL) was stirred in a microwave reactor at 140° C. for 5 hours and at 160° C. for 10 hours. The mixture was reduced in vacuo and ethyl acetate (50 mL) added. The mixture was washed with water (50 mL), brine (50 mL), dried (MgSO4), and reduced in vacuo to give a brown oil which was chromatographed on silica, eluting with 0-10% methanol in ethyl acetate, to give the desired compound as a white foam (64 mg).
