Versuchsvorschrift

To a solution of crude Part A 4-methyl-2′-hydroxybenzhydrol (9.7 g containing no more than 40 mmol) in 175 mL of MeOH was added 0.59 g of 10% Pd/C and 1.75 mL of TFA. The suspension was stirred for 40 hr under 1 atmos. H2, filtered through celite and concentrated to yield 8.6 of crude 2-(4′-methylbenzyl)phenol as an oil.
