実験手順
A suspension of 2,7-dibromo-4-methoxybenzothiazole (1.8 g) and morpholine (10 ml) in tetrahydrofuran (10 ml) was heated at 80° C. for 2 hours. The solvent was removed in vacuo and the residue partitioned between ethyl acetate (100 ml) and water (100 ml). The organic layer was dried over magnesium sulphate (3 g), filtered and the filtrate evaporated in vacuo to yield an off white solid. This was purified by recrystallisation from ethyl acetatelhexane to yield the title compound as a white solid (1.2 g). TLC Rf 0.39 (50% ethyl acetate in hexane).
