Versuchsvorschrift

To a solution of N-[2-(5-fluoro-pyridin-3-yl)-4-methyl-thiazol-5-yl]-2-methyl-3-methylsulfanyl-propionamide (0.250 g, 0.76 mmol) in dichloromethane (3.07 ml) at 0° C. was added cyanamide (0.064 g, 1.53 mmol) and iodobenzenediacetate (0.272 g, 0.84 mmol) and subsequently stirred at room temperature for 1 hour. The reaction was concentrated to dryness. The crude material was purified by silica gel column chromatography (10% methanol/ethyl acetate) to give the desired product as a light yellow solid (0.220 g, 60%): mp 75-81° C.; 1H NMR (400 MHz, CDCl3) δ 9.85 (s, 1H), 8.94-8.70 (m, 1H), 8.57-8.34 (m, 1H), 8.07-7.77 (m, 1H), 3.69-3.40 (m, 2H), 3.22-3.00 (m, 1H), 2.92-2.77 (m, 3H), 2.50 (m, 3H), 1.49 (m, 3H); ESIMS m/z 363.9 (M-2).
