Reaction Steps

A mixture of 5-benzyloxy-1-cyclopropylmethyl-2-difluoromethyl-1H-pyridin-4-one (3.0 g, 9.82 mmol) and 10% Pd/C (300 mg) in methanol (90 mL) was subjected to hydrogenation in a Parr apparatus under a 15 psi hydrogen pressure for 27 min. Work-up as described above for the cyclopropyl derivative, afforded the title product (1.76 g, 83% yield) after vacuum oven drying. HPLC purity (peak area percent) of the title compound is 99.5% at λ=288 nm using HPLC Method 1 as described above.
