This compound can be prepared by three different related ways: 1) By condensation of 1-methoxy-2-aminoindane (I) with 3-bromopropyl diethylamine (II) by means of sodium amide in refluxing toluene (1). 2) The reaction of (I) with 1-chloro-3-bromopropane (III) by heating at 100 C gives the corresponding N-(3-chloropropyl) derivative (IV), which is then condensed with diethylamine by means of NaI in refluxing ethanol (2). 3) By condensation of 1-methoxy-2-indanyl methanesulfonate (V) with N-(diethylaminopropyl)aniline (VI) in refluxing ethanol (2).
