  • 2-hydroxy-3-phenoxy-3, 3-diphenylpropinate (5) was prepared from benzophenone via Darzens, methanolysis and hydrolysis reaction. The compound (5) was salified with (S)-dehydroabietylamine (7) and diasterotropic resolution was carried out to provide the key intermediate (S)-2-hydroxy-3-methoxy-3, 3-diphenylpropionic acid (6). Compound (6) was condensed with 2-methylsulfonyl-4, 6-dimethylpyrimidine and 2-methoxysulfonyl4, 6-dimethylpyrimidine to afford ambrisentan (1) and darusentan (7… CONTINUE READING
