A facile and large-scale preparation of the antitumor agent R116010 has been developed. The new synthetic process requires four steps: (i) Friedel−Craftsreaction of N-phenyl-2-benzothiazolamine with 2-chloropropionyl chloride, (ii) conversion of the α-chloroketone into the corresponding α-(dimethylamino)ketone and resolution of the latter, (iii) reduction of the chiral aminoketone with resultant formation
