| titleOfInvention | A kind of method for synthesizing razaxaban key intermediate |
| abstract | The invention discloses one kind to synthesize razaxaban key intermediate (S) 2 { [base of 2 oxygen 3 (4 (3 oxygen morpholine) phenyl) oxazolidine 5] methyl } iso-indoles 1, the method of 3 diketone, 4 (4 first ammonia alkenyl phenyl) 3 morpholones and (S) { 1 (chloro-carbonic acid ester group) 2 [2 (1,3 dioxy iso-indoles) base] ethyl } halide salt are carried out into ring closure reaction to produce.This method is easy to operate, raw material is easy to get, yield may be up to 90% or so, obtained (S) 2 { [base of 2 oxygen 3 (4 (3 oxygen morpholine) phenyl) oxazolidine 5] methyl } iso-indoles 1,3 diketone purity are good, purity may be up to more than 98%, be suitably applied industrialized production. |
