Into a 1-liter magnetically stirred autoclave is placed 489 grams of ethyl-p-hydroxybenzoate having the structure: ##STR139## and 5% palladium on carbon catalyst (4 grams). The autoclave is sealed and hydrogenated at 125°-140° C. and 50 psig hydrogen pressure until the uptake of hydrogen is approximately 70% of theory. GLC analysis indicates that the reaction product at this point contains 71% ketone having the structure: ##STR140## 7.6% alcohol having the structure: ##STR141## and 20% starting material having the structure: ##STR142##
