Following the procedure of Example 2, Step C, 1-(3-(benzyloxy)pyridin-2-yl)thiourea (525 mg, 2.02 mmol), 1-bromobutan-2-one (428 mg, 2.83 mmol), and triethylamine (0.480 mL, 3.44 mmol) were reacted in ethanol (20 mL) to provide N-(3-(benzyloxy)pyridin-2-yl)-4-ethylthiazol-2-amine (609 mg) as a yellow oil. The HCl salt was prepared according to Example 3, Step C, to provide N-(3-(benzyloxy)pyridin-2-yl)-4-ethylthiazol-2-amine hydrochloride (585 mg, 83%) as a white powder. 1H NMR (d6-DMSO) δ 7.97 (d, 1H), 7.59-7.61 (m, 3H), 7.35-7.42 (m, 3H), 7.12 (m, 1H), 6.86 (s, 1H), 5.34 (s, 2H), 2.67 (q, 2H), 1.23 (t, 3H). Mass spectrum (apci) m/z=312 (100) (M+H-HCl).
