Reaction Steps

Intermediates 10 to 18 were prepared by treatment of the appropriate aminoheterocycle intermediate with 1 equivalent of phenylchloroformate in dry CH3CN and 1 equivalent of pyridine. The reagents were stirred at rt for 4 h, diluted with EtOAc, washed with NaHCO3, and dried over MgSO4. The material was purified by FCC to provide pure phenyl carbamate intermediates.
