Participants

Reaction Steps

Compound 2-22 (442 mg, 0.75 mmole), 4 mL of anhydrous chloroform and 400 mg of EDAC were stirred at 60° C. for 1 hr. The reaction mixture was condensed and chromatographed by HPLC. Combined fractions containing the desired product (MH+=899) were acidified by addition of 5 mL of 1N HCl and evaporated to dryness. The product was dissolved in distilled water and lyophilized to give 530 mg (68%) of white title compound.
