Reaction Steps
938 mg (3.07 mmol) of the compound from Example 87A were initially charged in 40 ml of dichloromethane and cooled to 0° C., and admixed with 1.28 ml (0.93 g, 9.22 mmol) of triethylamine and 0.62 g (3.07 mmol) of 4-nitrophenyl chloroformate. The reaction mixture was allowed to warm up slowly to RT and stirred at RT for 16 h. It was washed repeatedly with water, dried over sodium sulphate, filtered and concentrated under reduced pressure. This gave 1.21 g of crude product in 85% purity (LC-MS), which was reacted without any further purification steps.
