Reductive amination of 6-methoxy-1-indanone (I) with piperazine (II) in the presence of titanium isopropoxide and NaBH4 furnishes the indanyl piperazine (III). Racemic amine (III) is then resolved employing (S)-10-camphorsulfonic acid to provide the (R)-enantiomer (IV). Condensation of the optically active piperazine (IV) with ethyl isocyanate then affords the target urea (1-3).
