A solution of acetic acid 2-benzo[1,3]dioxol-5-yl-1-(6-methyl-pyridin-2-yl)-2-oxo-ethyl ester (80 mg, 0.26 mmol), ammonium acetate (200 mg, 2.6 mmol, 10 equiv) in acetic acid (4 mL) was heated to 105° C. for 3 hours. The resulting reaction mixture was concentrated in vacuo, and reverse phase high pressure liquid chromatography (a gradient from 5-30% acetonitrile in 0.1% aqueous formic acid) provided 2-(4-Benzo[1,3]dioxol-5-yl-2-methyl-oxazol-5-yl)-6-methyl-pyridine (15.9 mg, 21%).[LCMS: Rt=2.10 min; M+H=295.2]
