Reaction Steps

Dibutyltin diacetate (0.004 ml) is added to a solution of the above alcohol (0.42 g, 2.0 mmol) in 1.5 ml of DMF and the mixture is chilled in an ice bath. Ethyl isocyanate (0.18 ml, 2.2 mmol) is then added and the mixture is allowed to warn slowly to RT. The mixture is then poured into ether and water containing 10% potassium dihydrogen phosphate. The aqueous phase is extracted with ether, and the combined organic phases are washed with water and with brine, dried, filtered and the solvent is removed in vacuo to give O-2-[4-(1-methylpropoxy)phenoxy]-ethyl N-ethylcarbamate (compound 30, Table A).
