実験手順

Cyclohex-3-enyl-carbamic acid tert-butyl ester (Kampferer, P.; Vasella, A. Helvetica Chimica Acta 2004, 87, 2764-2789) (3 g, 15.2 mmol) and 2-bromoethyl methyl ether (1.43 ml, 15.2 mmol) were treated overnight to the method of Example 7 Step A. After work up and chromatography of the reaction mixture (silica, cyclohexane/ethyl acetate=7/1) the title compound (Rf=0.33, 1.2 g, 31% yield) was obtained as colorless solid.
