Participants

Reaction Steps

In Scheme 6, Step A, a phenyl thiazolo-pyridinone of formula (22) is coupled with a phenyl bromide of formula (25a) or (25b) to give a thiazolo-pyridinone of formula (19) or formula (I). The reaction takes place in an inert solvent such as THF, or preferably dioxane with an inorganic base added, such as cesium carbonate. A copper catalyst is used, such as copper (I) iodide in the presence of sym-dimethylethylene diamine. The reaction is heated at a temperature of about 70° C. to the reflux temperature of the solvent.
