実験手順

Substitution of 38 grams (0.5 moles) of 1,3-propanediol for the 1,6-hexanediol of Example 3 and heating the mixture for 5 hours yielded after workup 9.4 grams (35.5% yield) of 3-(3,5-di-tert.-butyl-4-hydroxyphenyl) propanol. The product is a pale yellow oil of a boiling point 135°-140° C. at 0.15 mm. of mercury which crystallized on standing to give a solid with a melting point of 67.5 to 69° C.
