Reaction Steps

Ethyl 3,5-bis(1,1-dimethylbutyl)-4-hydroxycinnamate was prepared by heating a mixture of 29 grams of 3,5-bis(1,1-dimethylbutyl)-4-hydroxybenzaldehyde, 40 grams of ethyl hydrogen malonate, 50 milliliters pyridine and 3 milliliters of piperidine at 90° to 95° C. for 7 hours. The reaction mixture was poured into a solution of 50 milliliters of concentrated hydrochloric acid in 100 milliliters of water. The oil which precipitated was separated by extraction with petroleum ether and the extract was stripped under vacuum to a pot temperature of 50°C./14 mm. The viscous residue weighed 39 grams.
