Reaction Steps
To a solution of 2-phenylcyclopropanecarboxylic acid (1.0 g, 6.17 mmol) in dry toluene (20 mL) was added triethylamine (934 mg, 9.26 mmol) and DPPA (2.0 g, 7.41 mmol) under N2, and the reaction mixture was refluxed for 3 h. The solution was concentrated to give (2-isocyanatocyclopropyl)benzene (800 mg), which was used for the next step without further purification.
