Reaction Steps

A mixture of 3-({(1S)-2-[(difluoromethyl)oxy]-1-methylethyl}oxy)-5-hydroxy-N-(1-methyl-1H-pyrazol-3-yl)benzamide (110 mg, 0.32 mmol), 5-(azetidin-1-ylcarbonyl)-2,3-dichloropyridine (75 mg, 0.32 mmol) and potassium carbonate (89 mg, 0.64 mmol) in acetonitrile (5 mL) was stirred in a ‘Biotage initiator Microwave’ at 160° C. for 3 hours. The solvent was removed in vacuo and ethyl acetate (50 mL) added to the residue which was washed with water (20 mL), brine (50 mL), dried (MgSO4), filtered and the solvent removed in vacuo to give a yellow oil. The residue was chromatographed on silica, eluting with a gradient of 50-100% ethyl acetate in isohexane, to give the desired compound (92 mg). 1H NMR δ (CDCl3): 1.40 (d, 3H), 2.41 (quin, 2H), 3.81 (s, 3H), 4.01 (mult, 2H), 4.26 (t, 2H), 4.38 (t, 2H), 4.67 (sextet, 1H), 6.29 (t, 1H), 6.82 (d, 1H), 6.96 (t, 1H), 7.27 (t, 1H), 7.31 (d, 1H), 7.38 (t, 1H), 8.18 (d, 1H), 8.26 (d, 1H), 8.77 (s, 1H), m/z 536 (M+H)+
