6-Bromo-2-(4-tert-butyl-cyclohexyloxy)-quinoline (115 mg, 0.317 mmol) in tetrahydrofuran (2.6 mL, 32 mmol) was added 2.0 M of n-butyllithium in cyclohexane (0.48 mL, 0.95 mmol) at −78° C. and was stirred for 15 min. N,N-dimethylformamide (0.12 mL, 1.6 mmol) was added and was stirred for 30 minutes. When the reaction completed, 1 M HCl was added and after 5 min at −78° C., sat. NaHCO3 was added and extracted with EtOAc. The organic layer was concentrated and purified by silica gel chromatography using PE/EA (0-50%) as eluent to give product as a gel (30.6 mg, 31%). LCMS Rt=2.49 min m/z=312.51 ([M+1], 100%).
