| titleOfInvention | Method of production and method of separation of 2,4'-dipyridyl derivatives and methods of production of benzoxazepine derivatives and salts thereof |
| abstract | PCT No. PCT/JP98/02264 Sec. 371 Date Jan. 21, 1999 Sec. 102(e) Date Jan. 21, 1999 PCT Filed May 22, 1998 PCT Pub. No. WO98/52922 PCT Pub. Date Nov. 26, 1998A method of production of 2,4'-dipyridyl derivatives by a cross coupling reaction of a 2-halopyridine derivative and a 4-halopyridine using a nickel complex catalyst and a method of separation of a 2,4'-dipyridyl derivative from a mixture of dipyridyl isomers containing a 2,2'-dipyridyl derivative, 2,4'-dipyridyl derivative, and 4,4'-dipyridyl by using a dilute aqueous copper sulfate solution to insolubilize and remove the 2,2'-dipyridyl derivative and 4,4'-dipyridyl are disclosed. |
