Reaction Steps

To a solution of 2-[4-(1-methylpropoxy)phenylthio]-ethylamine (2.21 g, 8.65 mmol) in 25 ml of ether, at 0° and under N2, is added ethyl chloroformate (0.52 g, 4.76 mmol) by syringe, followed by addition of 10% aqueous sodium hydroxide (3.5 ml) and additional ethyl chloroformate (0.51 g, 4.76 mmol). After 15 min., the reaction is worked up by addition of water and extraction with ether. The combined organic phases are washed with 1N sulfuric acid, with water and with brine, dried and filtered, the filtrate is concentrated in vacuo and the product is purified by prep. TLC to give ethyl N-{2-[4-(1-methylpropoxy)-phenylthio]ethyl}carbamate (compound 76, Table A).
