Procedure

A mixture of potassium ethylxanthogenate (6.25 g) and 2-[2-(4-amino-3-hydroxyphenyl)ethyl]-3,7-dimethylimidazo[1,2-a]pyridine (10.0 g) in ethanol (80 ml) was refluxed for 3 hours with stirring. The resulting precipitate was collected by filtration to give potassium 6-[2-(3,7-dimethylimidazo[1,2-a]pyridin-2-yl)ethyl]-2-benzoxazolethiolate (8.28 g).
