Method for preparing diamine precursor compound |
| abstract |
Provided is an inexpensive, simple, and efficient method for preparing, from a starting material, a nitro compound constituting a diamine precursor compound which is a starting material for producing a polyamic acid and/or polyimide. Compound (1) is reacted according to reaction formula (1) with di-tert-butyl dicarbonate ((Boc) 2 O) to produce compound (2) (1) (where R 1 represents -CH 2 COOR or -CH 2 Ph(-Z) m (where Z is a substituent group for a phenyl group (Ph) and m ranges from 0 to 5), and R represents a lower alkyl group or alkali metal atom), compound (2) is then reacted according to reaction formula (2) with H-A-CH 2 -X to produce compound (3) (2) (where A represents -C≡C- or -CH=CH-, and X represents a leaving substituent group), and compound (3) is then subjected to a coupling reaction according to reaction formula (3) with compound (4) to produce compound (5) (3) (where Y represents a leaving substituent group). |
