Reaction Steps

2-(2-Difluoromethyl-phenyl)-4,4,5,5-tetramethyl-[1,3,2]dioxaborolane (34 mg, 0.11 mmol), 1-[4-(3-Chloro-phenyl)-piperazin-1-yl]-2-hydroxy -4-methyl-pentan-1-one (34 mg, 0.13 mmol), Pd(Ph3P)4 (1.3 mg, 10 μmol), K2CO3 (30.4 mg, 0.22 mmol), CH3CN (900 μL), and H2O (100 μL) were sealed in a microwave vessel and heated by microwave irradiation at 150° C. for 10 minutes. The reaction was filtered and purified by reverse phase HPLC (10%-99% CH3CN (0.035% TFA)/H2O (0.05% TFA)) to give 2. LCMS: m/z 403.7 (M+H)+ at 3.72 minutes (10% -99% CH3CN/H2O), (10%-99% CH3CN (0.035% TFA)/H2O (0.05% TFA)).
