In isopropyl alcohol; at 80℃; for 16h; | As shown in step 4-i of Scheme 4, acetylisothiocyanate (6.824 g, 67.48 mmol) was added to a solution of 6-bromo-2-chloropyridin-3 -amine (14.0 g, 67.48 mmol) in isopropanol (300 mL). The reaction was heated for 16 hours at 80 0C. LCMS analysis indicated that the resulting mixture contained 85% desired product and 15% intermediate thiourea. The reaction mixture was cooled to RT, filtered, and the filtration cake washed with saturated sodium bicarbonate solution and brine. The solid was air dried to yield N-(5- <n="36"/>bromothiazolo[5,4-6]pyridin-2-yl)acetamide (Compound 1005, 12.0 g): 1H NMR (DMSOd6) delta 8.10(d, IH), 7.68(d, IH), 2.3(s, 3H). |
