Abstract : Water soluble coumarin, and azacoumarin compounds are prepared by a four step method involving (1) the formation of the benzylaminophenol or benzylaminohydroxypyridine, (2) the formation of a coumarin or azacoumarin, (3) sulfonation of the coumarin or azacoumarin and (4) neutralization of the sulfonate with sodium bicarbonate. The compounds are useful as water-soluble lasing dyes.
