Reaction Steps
Compound 74 (14.0 g, 0.021 mol) was mixed with LiOH (1.24 g, in 15 mL water), THF (100 mL), MeOH (20 mL) and a catalytic amount of tetrabutylammonium iodide. This mixture was heated at reflux overnight and most of the solvent was evaporated. The residue was acidified with concentrated HCl (30 mL). The resultant solid was collected by filtration, washed thoroughly with water and vacuum dried to yield compound 75 (12.5 g, 97.4% yield). M.p. 315.6-318.5° C.
