Reaction Steps

To a suspension of 1-(2-(4-fluorophenyl)thiazol-5-yl)-1-(pyridin-4-yl)ethanol (2 g, 6.6 mmol) in ethanol (60 mL) was added benzenesulfonic acid (1.05 g, 6.6 mmol) slowly at 0° C., and then the mixture was stirred for 1 hour at room temperature. The reaction mixture was concentrated, the solid obtained was washed with hexane (10 mL) to afford 4-(1-(1-(2-(4-fluorophenyl)thiazol-5-yl)-1-(pyridin-4-yl)ethanol benzenesulfonic acid salt as off-white solid (1.3 g, 43% yield), HPLC purity 99.6%, mp 165-167° C. 1H NMR (400 MHz, DMSO-d6): 8.81 (d, 2H), 8.04 (d, 2H), 7.93-7.89 (m, 3H), 7.57 (d, 2H), 7.33-7.28 (m, 5H), 7.09 (br s, 1H), 2.00 (s, 3H); LC-MS m/z calculated for [M+H]+301.07. found 301.1.
