実験手順
A stirred mixture of the product from Step 2 (0.738 g, 0.00538 mol), diphenylcyanocarbonimidate (1.28 g, 0.00538 mol) and ethylene glycol dimethyl ether (40 ml) was kept, under nitrogen, at ambient temperature (25° C.) for 7 hours. The mixture was concentrated and the residue was used in the next step without further purification.
