Reaction Conditions

Reaction Steps

2,4-Di-t-butylphenol (20.63 gr., 0.1 mole), paraformaldehyde (3.0 gr., 0.1 mol), boric acid (6.18 g., 0.1 mol) and toluene (50 ml.) were charged into a flask and heated at 80° C. under nitrogen for 48 hours. The mixture was filtered and the solvent removed to provide a brown oil. This oil was dissolved in ether and stirred with an equal volume of 1 N HCl for 2 hours. The ether layer was removed, washed with water, dried (MgSO4) and evaporated to form a soft yellow solid. This solid was stirred in pentane and then filtered to afford a white solid with a melting point of 97°-99° C. The structure was confirmed by NMR and FD/MS.
