Reaction Steps

2-Mercaptobenzoxazole (15.2 g; 0.1 mol) was dissolved in ethanol (200 ml); NaOH (4.0 g; 0.1 mol) dissolved in water was added thereto. The reaction mixture was refluxed for 30 minutes, then 3-chloropropylamine (9.3 g; 0.1 mol) dissolved in ethanol (50 ml) was added. The mixture was refluxed for 90 minutes, cooled, filtered from the salt and the solvent was evaporated under reduced pressure. The residue was purified by silica gel chromatography, eluting with methanol/ether (1:3), (15.0 g; 71.6% yield).
