Procedure
Methanesulfonic acid (53.1 mg, 0.5 mmol) was added to a solution of 544-methoxyphenyl)-2,2-dimethyl-4-(4-((5-methylimidazo[1,2-a]pyridin-2-yl)methoxy)phenyl)furan-3(2H)-one (250 g, 0.5 mmol) in DCM (2.5 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 5-(4-methoxyphenyl)-2,2-dimethyl-4-(4-((5-methylimidazo[1,2-a]pyridin-2-yl)methoxy)phenyl)furan-3(2H)-one methanesulfonate (240 mg, 82.7%) as white solid: 1H NMR: 500 MHz, DMSO-d6: δ 7.95 (s, 1H), 7.6 (d, 2H), 7.4 (d, 1H), 7.25 (t, 1H), 7.2 (d, 3H), 7.15 (d, 2H), 7.0 (d, 2H), 6.8 (d, 1H), 5.2 (s, 2H), 3.85 (s, 3H), 2.6 (s, 3H), 2.5 (s, 3H), 1.25 (s, 6H), HPLC: (98.4%, Condition-A).
