In a further procedure, styrene oxide (XV) was condensed with 2-(benzylamino)ethanol (XXVIII) to give amino diol (XXIX). After chlorination of (XXIX) using SOCl2 and DMAP, dichloro derivative (XXX) was condensed with 2-aminobenzyl alcohol (X) yielding piperazine (XXXI). Cyclization of (XXXI) in hot sulfuric acid afforded the tetracyclic compound (XXXII). The N-benzyl group of (XXXII) was then removed by treatment with butyl chloroformate producing carbamate (XXXIII), which was further hydrolyzed and decarboxylated to (XXXIV) under basic conditions. Finally, methylation of the secondary amine (XXXIV) was performed by reductive alkylation with formaldehyde either in the presence of formic acid under Leuckart-Wallach conditions or by catalytic hydrogenation
