3-Aminobenzyl alcohol → HCID 59020664, compound

Participants

Reaction Steps

3-(3-(hydroxymethyl)phenylamino)-2-nitroacrylaldehyde (4.3 g, 19.4 mmol) was placed in 20 mL HOAc. 4.8 g of 3-aminobenzyl alcohol (4.8 g, 38.7 mmol) was dissolved in 5 mL conc HCl, then 20 mL HOAC was added to the HCl solution. This mixture was added to the reaction flask containing the 3-(3-(hydroxymethyl)phenylamino)-2-nitroacrylaldehyde in HOAc. The mixture was heated to reflux under nitrogen and after 20 min, benzene thiol (0.19 mL, 0.19 mmol) was added. The mixture was refluxed for 28 h (m/z=208.1). After allowing to cool, acid was removed under vacuum. The residue was dissolved in EtOAc/MeOH and loaded on a silica gel cartridge. Purification by column chromatography on silica gel using hexane/EtOAc (0-50%) then 10% MeOH/EtOAc as eluent gave the product (500 mg, 9%) as a brown solid.
