Reaction Steps

A mixture of 4-mercaptobutyric acid (0.72 g.) a 50% w/w dispersion of sodium hydride in mineral oil (0.58 g.) and 2-ethoxyethanol (5 ml.) was treated with 2-amino-6-bromopyridine (0.35 g.) and the mixture was heated under reflux for 18 hours and then evaporated to dryness. The residue was partitioned between water and EtOAc and the aqueous phase was neutralised with HOAc. The precipitated yellow solid was collected to give 4-(6-aminopyrid-2-ylthio)butyric acid (0.27 g.) which was used without further purification.
