HCID 66794299, compound → 7-(2-Chloro-ethoxy)-2-(4-amino-phenyl)-benzo[d]imidazo[2,1-b]thiazole

Participants

Reaction Steps

A mixture of 7-(2-chloro-ethoxy)-2-(4-nitro-phenyl)-benzo[d]imidazo[2,1-b]thiazole (1 equivalent) and 10% Pd/C (0.05-0.1 equivalents) in a mixture of MeOH and THF under 1 atmosphere of hydrogen gas is stirred at rt until the reaction is substantially complete as monitored by LCMS or TLC. The mixture is filtered through Celite and concentrated under reduced pressure. The residue is purified by silica gel flash chromatography to afford 7-(2-chloro-ethoxy)-2-(4-amino-phenyl)-benzo[d]imidazo[2,1-b]thiazole.
