To a mixture of 1,1,1,3,3,3-hexafluoro-2-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)propan-2-ol (110 mg, 0.30 mmol) and N-(6-chloro-5-methylpyridin-2-yl)-1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)cyclopropanecarboxamide (73 mg, 0.20 mmol) in DME (2 mL) and 2 M Na2CO3 (0.2 mL) was added Pd(PPh3)4 (12 mg, 0.010 mmol). The mixture was heated in microwave oven at 120° C. for 30 min. The mixture was partitioned between ethyl acetate and H2O, and the aqueous layer was extracted with ethyl acetate (3×). The combined organic layers were washed with brine, dried over MgSO4, and concentrated under reduced pressure. The residue was purified by column chromatography (10-20% ethyl acetate-hexane) to yield 1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)-N-(6-(4-(1,1,1,3,3,3-hexafluoro-2-hydroxypropan-2-yl)phenyl)-5-methylpyridin-2-yl)cyclo-propanecarboxamide (86 mg, 75%). 1H NMR (400 MHz, CDCl3) δ 8.03 (d, J=8.4 Hz, 1H), 7.69 (d, J=8.3 Hz, 2H), 7.65 (s, 1H), 7.54-7.48 (m, 1H), 7.45 (d, J=8.6 Hz, 2H), 7.13 (td, J=10.0, 1.7 Hz, 2H), 6.99 (d, J=8.2 Hz, 1H), 2.21 (s, 3H), 1.68 (q, J=3.6 Hz, 2H), 1.09 (q, J=3.6 Hz, 2H).
