Reaction Steps

To a solution of methyl (3R,5S,8S)-23-iodo-8-isopropyl-7-oxo-2,28-dioxa-6,9,11,12,25-pentaazapentacyclo[17.6.2.13,6.110,13.022,26]noncosa-1(25),10,12,19,21,23,26-heptaene-5-carboxylate (from Step 2) in THF/H2O (1/1 v/v) was added LiOH (4 eq). The resulting reaction mixture was stirred at RT for 2 h and then treated with 1N aq. HCl until pH=2 was reached. Aqueous phase extracted with EtOAc and organic layer dried over Na2SO4 to get a white solid. MS (ES+) C26H30IN5O5 requires: 619. Found: 620 (M+H+).
