Process for producing 5-fluorooxyindole and for producing intermediates therefor |
abstract |
The present invention discloses a process for preparing 5-fluorooxindole represented by the formula (3): n n n which comprises (A) a first step of cyclizing 2-(5-fluoro-2-nitrophenyl)malonic acid diester represented by the formula (1) : n n n wherein R 1 and R 2 may be the same or different from each other and each represents a group which does not participate in the reaction, n under reductive conditions to form 5-fluorooxindole-3-carboxylic acid ester represented by the formula (2): n n n wherein R 1 has he same meaning as defined above, and n (B) then, a second step of decarboxylating the 5-fluorooxindole-3-carboxylic acid ester, n and a process for preparing its synthetic intermediates. |
