Participants

Reaction Steps

N,N'-dicyclohexylcarbodiimide (15 mg) was added to a solution of 8-β-aminoethyltheophylline (5 mg) and carboxyfluorescein (5 mg) in 0.5 ml of pyridine. The reaction was allowed to proceed for two hours at room temperature and the reaction product was purified twice employing silica gel thin-layer chromatography using a thin chloroform:methanol (2:1) mixture as developing solvent to yield an 8-β-amino ethyltheophylline-carboxyfluorescein conjugate of the formula: ##STR10##
