Example 17: (E)-3-[3′-Adamantan-l-yl-4′-(l,3-dioxo-l,3-dihydroisoindol-2- ylmethoxy)-biphenyl-4-yl] -acrylic acid ST5632AA1; STEP 1: A solution of (E)-3-(3′-adamantan-l-yl-4′-hydroxybiphenyl-4-yl)acrylic acid tert-hutyl ester (200 mg, 0.464 mmol), N-chloromethylphthalimide (91 mg, 0.464 mmol), K2CO3 (70 mg, 0.464 mmol) and NaI (70 mg, 0.464 mmol) was stirred overnight at RT in the dark. The solvent was evaporated and the residue was taken up in EtOAc. The organic phase was washed with water, dried over Na2SO4, filtered and evaporated under reduced pressure. 3-[3′- Adamantan-l-yl-4′-(l,3-dioxo-l,3-dihydroisoindol-2-ylmethoxy)-biphenyl-4- yl] acrylic acid tert-hutyl ester was obtained after purification on silica gel (EtOAc/hexane 15:85) in 55%yield (150 mg).1H NMR (DMSO-ds) delta: 7.30-8.05 (m, 12H); 6.55 (d, J = 16 Hz, IH); 5.70 (s, 2H); 2.05 (s, 6H); 1.95 (s, 3H); 1.60 (s, 6H); 1.50 (s, 9H).
