Reaction Steps

A suspension of 1-(2-(4-fluorophenyl)thiazol-5-yl)-1-(pyridin-4-yl)ethanol (2 g, 10 mmol) in ethanol (6 mL) and isopropyl alcohol (30 mL) was cooled to 0° C., and to this mixture was added 6N HNO3 (6 mL) in 30 mL of isopropyl alcohol. The reaction mixture was stirred for 1 hour at room temperature. The solid formed was filtered and washed with hexane (10 mL) to afford 4-(1-(2-(4-fluorophenyl)thiazol-5-yl)-1-hydroxyethyl)pyridin-1-ium nitrate as an off-white solid (2.3 g, 63% yield), HPLC purity 99.8%, mp 188-191° C. 1H NMR (400 MHz, DMSO-d6): 8.85 (d, 2H), 8.10 (d, 2H), 7.92 (t, 3H), 7.30 (t, 2H), 7.13 (br s, 1H), 2.01 (s, 3H); LC-MS m/z calculated for [M+H]+ 301.07, found 301.1.
