Paragraph 0040; 0042, (2017/09/19)
The invention relates to a (R, S)-2-[ [5-(9- [...] carbonyl amino) dibenzo [A, D] cyclohepta-2-yl] oxy] acetic acid synthesis process, comprising the following steps: step one, O-carboxybenzaldehyde and Intergovernmental methoxylphenylboronic acetic acid in anhydrous sodium acetate under the catalysis of the reaction to obtain 2-(3-methoxy-vinyl) benzoic acid, Pd-C under the catalysis of the hydrogen reduction reaction-; step two, and SOCl 2 reaction to obtain 2-methoxy -10, 11-dihydro -5H-dibenzo [a, d] cycloheptene-5-one, then anhydrous AlCl 3 catalytic reflux reaction; step three, the return reaction of the intermediate product and bromine second grade acid benzyl ester for reaction; step four, the reduction reaction of the hydrogen gas, and then with Fmoc-NH 2 for reaction, to obtain. This invention, through optimization of the catalyst, is obviously improved the overall yield, effectively reducing the cost, is suitable for industrial mass synthesis application.

The present invention is directed to a compound represented by the following formula (I), STR1 and a linker for peptide synthesis using the above compound. When the linker of the present invention is used for the solid-phase peptide synthesis, it is possible to synthesize those peptides which are sensitive to acid and difficult to synthesize by conventional methods. Also, side reactions can be prevented, and the desired product is produced at a high purity because cleavage can be achieved under milder conditions or in shorter times. In other words, efficient peptide synthesis is possible.
