6-Bromo-2,2,4-trimethyl-1,2-dihydroquinoline (256 mg, 1.02 mmol) (Example 8) and 2,3-dimethoxyphenyl boronic acid (370 mg, 2.03 mmol) were combined in DMSO (2 mL). 2 M K3PO4 (1 mL) was added, followed by PdCl2(dppf) (50 mg). The contents were placed in a microwave reaction vessel assembly and irradiated at 120° C. for 15 minutes. The reaction was cooled to room temperature. Purification of the crude product by chromatography afforded 6-(2,3-dimethoxyphenyl)-2,2,4-trimethyl-1,2-dihydroquinoline (190 mg, 61%) as a white solid.
