A process for producing (R) -1,1,3-trimethyl-4-aminoindane comprising the following steps (A), (B) and (C). (R) -1,1,3-trimethyl-4-aminoindan and (S) -1,1,3-trimethyl- Step for obtaining 4-aminoindan (B): racemizing the (S) -1,1,3-trimethyl-4-aminoindan obtained in the step (A) or the step (C) to obtain 1,1,3-trimethyl- fair (C): The 1,1,3-trimethyl-4-aminoindane obtained in the step (B) was optically split and the (R) -1,1,3- Step of obtaining 1,3-trimethyl-4-aminoindan |
