Reaction Steps

The quinoxalin-2-one of the present example is prepared treating 6-hydroxy-3-thiophen-2-yl-1H-quinoxalin-2-one from Example 43 in DMF with bromomethyl benzene in the presence of K2CO3 at a temperature between 25° C. to 80° C. The resulting reaction mixture, after workup and purification, affords 6-benzyloxy-3-thiophen-2-yl-1H-quinoxalin-2-one.
