실험 절차

The preparation is analogous to Example 1 from 2.64 g (10 mmol) of 4-hydroxybenzoic acid 4-acryloyloxybutyl ester, 3.99 g (10 mmol) of 4′-(6-acryloyloxyhexyloxy)-3′-methoxybiphenyl-4-carboxylic acid, 0.12 g (1 mmol) of DMAP and 2.11 g (11 mmol) of EDC. Purification of the residue by chromatography on silica gel using cyclohexane/ethyl acetate (7:3) and recrystallisation once from ethanol yields 4′-(6-acryloyloxyhexyloxy)-3′-methoxybiphenyl-4-carboxylic acid 4-(4-acryloyloxybutoxycarbonyl)-phenyl ester.
