To a stirred solution of 4-hydroxy-4-methyl-1-(pyridin-4-yl) pent-2-yn-1-one (1.49 g, 0.007 mol) in ethanol (15 mL), diethylamine (0.511 g, 0.007 mol) in EtOH (15 mL) was added dropwise at RT. The mixture was then stirred for additional 40 min. The EtOH was evaporated and the mixture was diluted with EtOAc (100 mL). The organic layers were washed with water (50 mL) and brine (20 mL), dried over Na2SO4, filtered and concentrated in vacuo to afford 2,2-dimethyl-5-(pyridin-4-yl)furan-3(2H)-one (1.4 g).
