    • General procedure for the preparation of 1-carbamato-alkyl-2-naphthol derivatives: To a mixture of 2-naphthol (1 mmol), aldehyde (1 mmol), and methyl/benzyl carbamate (1.2 mmol), silica supported sodium hydrogen sulfate (0.05 g) was added. The mixture was stirred at 100 °C in an oil bath and the reaction was followed by TLC. After completion, the mixture was cooled to room temperature, and then ethanol was added to dissolve the precipitated product. The catalyst was filtered and the filtrate evaporated. Then, the solid product was purified by recrystallization from aqueous EtOH (20%). Spectral data are given below.
