N-(6-Chlorothiazolo[4,5-b]pyridin-2-yl)benzamide (364 mg, 1.256 mmol) in H2SO4 (4 ml, 75 mmol) was heated to 120° C. for 30 minutes, cooled to ambient temperature, basified with 10N NaOH and the resultant solids were collected by filtration to afford 6-chlorothiazolo[4,5-b]pyridin-2-amine (148 mg, 0.797 mmol, 63.5% yield) 1H NMR (500 MHz, DMSO-d6) δ ppm 8.19-8.24 (m, 2H) 8.09 (br. s., 2H).
