The present invention relates to a method for producing an isoindole derivative (compound (II)) with the following general formula (II):
(wherein R
1
and R
2
each independently represents a C
1-6
alkyl group) or a salt thereof, comprising the step of cyclizing, in a solvent, compound (I) with the following general formula (I):
(wherein R
1
and R
2
have the same meanings as R
1
and R
2
in formula (II) above) or a salt thereof, or their hydrate or solvate in the presence of a base (Step 1).
