| titleOfInvention | Method for producing polyalkylene glycol derivative having amino group at end, with narrow molecular weight distribution |
| abstract | The present invention provides a process for producing a narrow-dispersed polyalkylene glycol derivative having an amino group at the terminal in mild conditions. A process for producing a compound represented by the general formula (1) CH 3 O (CH 2 CH 2 O) n CH 2 CH 2 CH 2 NH 2 (n is an integer of 1 to 450) [Step 1] The formula (2) CH 3 O (CH 2 CH 2 O) k H Formula (3) from a compound of (k is an integer from 2 to 5), CH 3 O (CH 2 CH 2 O) k- 1 CH 2 CH 2 O - M + ; [Step 2] A step of obtaining a compound represented by the general formula (4) CH 3 O (CH 2 CH 2 O) n-1 CH 2 CH 2 O - M + from the compound of the general formula (3); [Step 3] A step of reacting a compound represented by the general formula (4) with acrylonitrile to obtain a compound represented by the general formula (5) CH 3 O (CH 2 CH 2 O) n CH 2 CH 2 CN; And [Step 4] A step of reducing the compound of the general formula (5) to obtain the compound of the general formula (1). |
