The reaction mixture was heated at 98° C. for 18 hours. After cooling to ambient temperature, the mixture was acidified by the addition of 6 N aqueous HCl, then saturated aqueous sodium bisulfite was added. The mixture was extracted with 2-propanol/CH2Cl2 (1:3). The organic extract was concentrated to afford the title compound.
