Reaction Steps

To a solution of the compound from EXAMPLE 2 in CH2Cl2 was added isobutyric chloride, triethylamine and a catalytic amount of DMAP. The mixture was stirred at room temperature for 2 hr. The solvent was removed and the residue was heated with 10 mL 2 N NaOH in 40 mL methanol at 50° C. for 1 hr. Methanol was removed under vacuum. The residue was diluted with water and the aqueous was extracted with ethyl acetate. The organic layer was washed with brine, dried (MgSO4) and the solvent was removed. The residue was purified by preparative TLC (80:20 EtOAc:hexane), 0.07 mg. M++1: 558.16.
