Reaction Steps
A mixture of the resultant aldehyde from Example 16E (1.0 equivalent), 2-aminopyridine (1.0 equivalent) and NaCNBH3 (1.5 equivalents) in methanouacetic acid is stirred until the reaction is judged complete by TLC analysis. The mixture is poured into aqueous NaHCO3 and extracted into ethyl acetate which is dried and evaporated. Chromatography of the residue on silica gel affords the title compound.
