Procedure

The product 2,6-bis-allylresorcinol (33.5 gm) was dissolved in methanol and hydrogenated under H2 Pressure (initial pressure 45 psig) over 10% Pd on carbon (300 mg). The reaction mixture was filtered through celite and reduced i. vac. The crude oil was flushed through a short SiO2 gel column eluting with ethyl ether. The resulting oil was purified by crystallization from hexanes:ether.
