Procedure

To a solution of the above amine (2.41 g, 10.0 mmol) in 10 ml DMF, cooled to 0° and under N2, is added potassium carbonate (1.66 g, 12.0 mmol) followed by dropwise addition of ethyl chloroformate (1.2 ml, 12.0 mmol) in 5 ml of DMF. After 1.5 hours, water is added and the aqueous phase is extracted with ether. The combined organic layers are washed with water and brine, dried, rotoevaporated and the residue is purified by column chromatography to give ethyl N-{2-[4-(1-methylpropylthio)phenoxy]ethyl}carbamate.
