Pyridine → O-2-[4-(1-methylpropoxy)phenoxy]ethyl N-ethyl-N-phenylsulfenylcarbamate

Participants

Reaction Steps

To O-2-[4-(1-methylpropoxy)phenoxy]ethyl N-ethylcarbamate (1.50 g, 5.34 mmol) and pyridine (1 ml, 11.75 mmol) in 20 ml of methylene chloride at RT is added phenylsulfenyl chloride (1.54 g, 10.70 mmol). The reaction mixture is stirred for 2 hours, after which it is poured into ice water and extracted with ether. The combined organic layers are washed with 10% HCl, with water until neutral and with brine and dried. After filtration and removal of the solvent, the product is purified by prep. TLC to give O-2-[4-(1-methylpropoxy)phenoxy]ethyl N-ethyl-N-phenylsulfenylcarbamate, MS m/e 390 (M+ +H) (compound 23, Table A).
