A microwave vial was charged with methyl cyano[6-(methylthio)-4-pyrimidinyl]acetate (Intermediate 14, 700 mg, 3.14 mmol), sodium chloride (1.0 g, 17.11 mmol), water (1 mL) and DMSO (19 mL). The mixture was stirred and heated at 160° C. for 50 minutes in the microwave. The reaction mixture was diluted with ethyl acetate (20 mL) and washed with brine. The organic layer was dried (sodium sulfate), filtered and concentrated under reduced pressure. The residue was dissolved in DCM (10 mL) and purified by column chromatography (Biotage SP4) eluting with a gradient of 0-100% ethyl acetate and iso-hexane. Fractions containing the suspected product were combined and concentrated under reduced pressure to give the title compound (292 mg) as a yellow oil;
