Reaction Steps

A mixture of isobutyl 4-(6-chloropyrimidin-4-yl)piperazine-1-carboxylate (0.10 g, 0.33 mmol), 2-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenol (87 mg, 0.11 mmol), Pd(PPh3)4 (3.8 mg, 3.3 μmol), K2CO3 (91 mg, 0.66 mmol), CH3CN (1 mL), and H2O (0.1 mL) was sealed in a microwave reactor vial. The reaction mixture was heated by microwave irradiation at 130° C. for two minutes. The reaction was filtered and purified by reverse phase HPLC (10%-99% CH3CN (0.035% TFA)/H2O (0.05% TFA)) to give isobutyl 4-(6-(2-hydroxyphenyl)pyrimidin-4-yl)piperazine-1-carboxylate. LC/MS: m/z 357.3 (M+H)+ at 2.72 min (10%-99% CH3CN (0.035% TFA)/H2O (0.05% TFA)).
