実験手順

To a suspension of 1.3 g (9 mmol) of 2-mercapto-4,5,6,7-tetrahydro-1H-benzimidazole in 20 ml of ethanol was added 1.35 g (7 mmol) of 2-methylaminobenzyl chloride hydrochloride for a period of 15 min. The solvent was distilled off, and the residue was shaken sufficiently with a combination of 1N aqueous sodium hydroxide and chloroform for performing extraction. The organic portion was taken out and then dried over anhydrous sodium sulfate. Chloroform was distilled off, and the residue was crystallized from ether/hexane to give 1.02 g of the desired compound as a pale brown crystalline product, yield 53%.
