실험 절차

Carbonyl diimidazole (1.94 g) was added to a stirred solution of the acid from step c) (3.64 g) in DMF (15 ml). Stirring was continued for 40 min at room temperature. To this solution was added 7-[2-aminoethyl]-4-hydroxy-1,3-benzothiazol-2(3H)-one hydrobromide (3.48 g) followed by triethylamine (1.7 ml). The whole was left overnight. The reaction mixture was then added slowly to a rapidly stirred mixture of 10% aqueous hydrochloric acid and ether (100 ml each). A pale yellow solid gradually settled out and was filtered off, washed with pentane and dried in vacuo. This provided the subtitled compound as a buff coloured material which was used in the next step without further purification.
