Reaction Steps

Ester 54 from above (1.7 g, 3.52 mmol) is treated with NaOMe (0.5M in methanol, 21 ml, 10.5 mmol) and heated under reflux for 24 hours. The solvent is then evaporated, the residue taken up in DCM and extracted with 1N-NaOH and brine. After drying and evaporation the crued is purified by chromatography on silicagel using DCM (saturated with ammonia) and MeOH (from 1% to 3%) to give a white powder.
