Versuchsvorschrift

A solution of 4-bromoacetylbenzoic acid (2.2 g, 10 mmol) in ethanol (50 mL) was treated with pyrid-3-ylthiourea (1.53 g, 1 mmol) and the mixture was refluxed for 3 hr. Solids were collected by filteration, washed with ether and dried to provide 4-(2-pyrid-3-ylaminothiazol-4-yl)benzoic acid (2.2 g, 74% yield). LC-MS: FAB LC-MS. 298.2 (M+H+).
