Procedure
Methanesulfonic acid (36 mg, 0.3 mmol) was added to a solution of 4-(5,5-dimethyl-3-(4-((5-methylpyridin-2-yl)methoxy)phenyl)-4-oxo-4,5-dihydrofuran-2-yl)benzonitrile (150 mg, 0.3 mmol) in DCM (5 ml) and diethyl ether (50 mL) at RT under an atmosphere of nitrogen. The reaction mixture was stirred at RT for 4 h upon which the solids were collected by filtration, washed with 20% DCM in diethyl ether, dried in vacuo to afford 4-(5,5-dimethyl-3-(4-((5-methylpyridin-2-yl)methoxy)phenyl)-4-oxo-4,5-dihydrofuran-2-yl)benzonitrile methanesulfonate (120 mg, 67.0%) as a white solid. 1H NMR: 200 MHz, DMSO-d6: δ 8.5 (s, 1H), 7.6 (d, 1H), 7.55 (d, 2H), 7.4 (d, 1H), 7.2 (d, 2H), 7.1 (d, 2H), 7.0 (d, 2H), 5.2 (s, 2H), 2.35 (s, 3H), 2.3 (s, 3H), 1.45 (s, 6H). HPLC: (98.3%, Condition-A).
