実験手順
A mixture of 5-(2-bromoethoxy)-2,3-dihydro-benzo[1,4]dioxine (1.2 g, 4.7 mmol) and 4,5-dimethyl-thiazol-2-ylamine (0.50 g, 3.9 mmol) was heated at 85° C. for 7 hours. The mixture was cooled to ambient temperature and the residue was recrystallized from ethanol to provide 0.18 g (13%) of the title compound.
