Procedure

A mixture of 4-{[3-Bromo-4-[(2,4-difluorobenzyl)oxy]-6-methyl-2-oxopyridin-1(2H)-yl]methyl}pyrimidine-2-carbonitrile trifluoroacetate (0.2 g, 0.00035 mol) potassium fluoride on aluminum oxide (0.25 g) in t-butanol (5.0 mL) was refluxed for 4 h under argon atmosphere. The reaction mixture was cooled, filtered the precipitate and washed with ethanol. The combined filtrate and washings were concentrated to dryness and the residue was purified by reverse-phase HPLC using 10-90% acetonitrile/water gradient (30 min) at a flow rate of 100 mL/min. The appropriate fractions (m/z=452) were combined and freeze dried to afford the title compound (0.05 g) as a white powder:
