Jh. Sun et Wf. Daneker, AN EFFICIENT SYNTHESIS OF ((9-FLUORENYL-METHOXYCARBONYL)AMINO)METHYL)BENZOIC ACID, Synthetic communications, 28(24), 1998, pp. 4525-4530
An efficient, two-step syntesis of the title compound 3 in 61% overall
yield is presented. The synthesis involves hydrazine removal of the N
-phthalimide protecting group of alpha-phthalimido-o-toluic acid (6),
followed by N-Fmoc formation with (9-fluorenylmethyl)succinimidyl carb
onate.
