Reaction Steps

A mixture of methyl 3-hydroxy-5-[(1S)-2-hydroxy-1-methylethoxy]benzoate (2.35 g, 10.39 mmol), 5-(azetidin-1-ylcarbonyl)-2,3-dichloropyridine (2.41 g, 10.39 mmol) and potassium carbonate (2.87 g, 20.8 mmol) in acetonitrile (20 mL) was stirred in a microwave reactor at 160° C. for 6 hours. The solvent was removed in vacuo and the residue partitioned between ethyl acetate (50 mL) and water (50 mL). The organic layer was washed with brine (50 mL), dried (MgSO4), and the solvent removed in vacuo. The crude oil was chromatographed on silica, eluting with 30-100% ethyl acetate in isohexane, to give the desired compound as a yellow oil (5.3 g).
