Reaction Steps

To a solution of compound 1f (2.11 g, 5.23 mmol) in CH2Cl2 (60 mL) was added 1-chloroethyl chloroformate (2.0 mL, 18.35 mmol) at 0° C. under N2. The mixture was stirred at 0° C. for 90 min and then MeOH (4 mL) was added. The mixture was refluxed for 1 h. Upon cooling, Et2O (50 mL) was added to the mixture. The resulting solid was collected by filtration and dried. The crude compound 1g was used in the next reaction without further purification. MS m/z (M+H+) 238.1.
