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 4-methylbenzenesulfonic acid (1.14 g, 6.6 mmol) slowly at 0° C., and then the mixture was stirred for 1 hour at room temperature. The solid that formed was filtered and washed with hexane (10 mL) to afford 4-(1-(1-(2-(4-fluorophenyl)thiazol-5-yl)-1-(pyridin-4-yl)ethanol 4-methylbenzenesulfonic acid salt as an off-white solid (1.9 g, 61% yield), HPLC purity 98.2%, mp 181-184° C. 1H NMR (400 MHz, DMSO-d6): 8.84 (d, 2H), 8.08 (d, 2H), 7.91 (t, 3H), 7.46 (d, 2H), 7.30 (t, 2H), 7.09 (d, 2H), 2.26 (s, 3H), 2.01 (s, 3H); LC-MS m/z calculated for [M+H]+301.07. found 301.1.
