Reaction Steps

In the same manner, 2-[4-(6-trifluoromethyl-2-quinoxalinyloxy)phenoxy]propionic acid chloride is prepared from the corresponding propionic acid and oxalyl chloride, and is then reacted with the sodium salt of methylacetoacetate to give methyl 2-acetyl-4-[4-(6-trifluoromethyl-2-quinoxalinyloxy)phenoxy]-3-oxopentanoate (XIV; X' is CF3 and X" is hydrogen). The pentanoate is then heated with sodium chloride and DMSO to yield 5-[4-(6-trifluoromethyl-2-quinoxalinyloxy)phenoxy]-2,4-hexanedione (XV; X' is CF3 and X" is hydrogen).
