To make it from indole, it sounds strange. Maybe, you meant 1-indanone? From indanone you can make Mannich reaction, substitute Alk2N to CN, protect the ketone as ketal, reduce CN to amine and deprotect. Or reduce both and reoxidize the alcohol (risk of polymerisation via imine formation).

Mr/Miss/Mrs Rajawat,

Please find as attachment sythetic roads for derivatives of your compound of interest. They are not via indole, because of it should perform indole ring opening and series of transformation of -NH2 to -COH to achieve 1H-inden-1-one skeleton. The shown roads are relatively limited towards the number of the steps approaches.
