Procedure

To a solution of (3aR,7S,10S,12R,21E,24aS)-7-cyclopentyl-N-{(1R,2S)-1-[(cyclopropylsulfonyl)carbamoyl]-2-ethenylcyclopropyl}-19-hydroxy-5,8-dioxo-1,2,3,3a,5,6,7,8,11,12,20,23,24,24a-tetradecahydro-10H-9,12-methanocyclopenta[18,19][1,10,3,6]dioxadiazacyclononadecino[11,12-b]quinoline-10-carboxamide (Example 17) (35 mg) in dichloromethane (0.44 mL) was added triethylamine (123 μl) followed by diethyl chlorophosphate (64 μl). The reaction mixture was stirred at room temperature until disappearance of the starting material. The reaction was quenched with water and extracted with ethyl acetate (3×). The combined organic fractions were dried over magnesium sulfate, filtered and concentrated. Purification by reverse phase HPLC (40-100% ACN/0.015% TFA-water) afforded the desired product (20 mg). LRMS (ES+) m/z 926.4 (M+H)+.
