Reaction Steps

A mixture of bis(2-tert-butoxycarbonylaminoethyl)amine (0.01 mol), 4-cyanobenzyl-bromide (0.01 mol), K2CO3 (0.05 mol), and CH3CN (70 mL) was heated at 60° C. for 10 hours. The resultant bis(2-tert-butoxycarbonylaminoethyl)amino-4-methylphenylcyanide was deprotected using HCl/ether, condensed with 2-acetyl pyridine (0.01 mol) in MeOH, and then reduced by NaBH4. After sequential treatments with pyridine-2-carboxaldehyde, NaBH4, and HCl, compound 110 was obtained in 75% overall yield.
