Procedure

The compound obtained in Example 160, Step A (25 mg, 0.069 mmol) was dissolved in dichloromethane (0.5 mL) to which was then added triethylamine (0.029 mL, 0.207 mmol) and isopropyl carbonochloridate (10.1 mg, 0.083 mmol). After 45 minutes the solvent was removed in vacuo and the residue purified by passing through a UCT (United Chemical Technologies) 2.5 g C-18 cartridge (#CEC181(2500)6) and eluting as follows:
