Reaction Steps

A solution of 4-(naphth-1-yl)-3-thiosemicarbazide (26 mg, 0.12 mmol) and 2,4-dihydroxybenzaldehyde (20 mg, 0.144 mmol) in dimethylformamide (1 mL) was shaken with 4 Å molecular sieves for 60 h. PS-TsNHNH2 resin (29 mg, 0.085 mmol) was added and shaking continued for 40 h, then the resin was filtered off. The solvent was removed under vacuum and the residue dissolved in ethanol. The solvent was again removed and the process repeated to give the title compound (7 mg, 18%) as a solid. MS (ES−) m/e 336 [M−H]−.
