Procedure

10% Palladium on carbon (15 mg) is added to a solution of [6-(2,6-diethyl-phenyl)-4-methoxy-2-methyl-pyridin-3-yl]-(3,4-dihydro-naphthalen-1-yl)-methanol (141 mg, 0.34 mmol, step 2, Example 29) in methanol (25 mL) and the reaction mixture is submitted to hydrogenation (Parr shaker) at 55 psi for 4 hours. The resulting mixture is filtered on celite and the filtrate concentrated in vacuo to give crude [6-(2,6-diethyl-phenyl)-4-methoxy-2-methyl-pyridin-3-yl]-(1,2,3,4-tetrahydro-naphthalen-1-yl)-methanol, which is used in the next step without further purification.
