Reaction Steps

Diphenylphosphoryl azide (0.54 mL, 2.53 mmol) and triethyl amine (0.35 mL, 2.53 mmol) were added dropwise to a solution of trans-2-ethoxycarbonyl-cyclopropane carboxylic acid (0.4 g, 2.53 mol) in toluene (5 mL) at room temperature. After 1 hour, the mixture was diluted with toluene (10 mL), washed with water (1×), 0.1N HCl (1×) and brine (1×), and dried (Na2SO4). The solution of trans-2-carboethoxy-cyclopropane carbonyl azide was heated at 100° C. for 1 hour producing a solution of the title compound which was used as is.
