Procedure
Into a round bottom flask was added compound 4 (500.0 mg, 1.51 mmol) and toluene (5.0 mL, 0.047 mol) under an atmosphere of nitrogen. Into the reaction mixture 1.0 M isopropyl chloroformate in toluene (1.6 mL) was added slowly at room temperature. The reaction mixture was stirred for another 2 hours to give desired compound 5 used for next step without purification.
