実験手順
N-[5-(3-Imidazol-1-yl-4-methanesulfonyl-phenyl)-4-methyl-thiazol-2-yl]-acetamide (AF2) (5.0 g, 13 mmol) is dissolved in 7M HCl (50 ml) and the solution is heated at 100° C. for 3 h. When cool the solution is brought to pH 8 by addition of aqueous NaOH whereupon the titled product precipitates. This is washed with ethanol followed by EtOAc, Et2O and dried.
