Reaction Steps

To a solution of 2-{[(4-{[4-chloro-3-(trifluoromethyl)phenyl]oxy}phenyl)methyl]thio}-5-(hydroxymethyl)-4(1H)-pyrimidinone (51 mg, 0.115 mmol) in dry DMF (3 mL) was added DIAD (0.034 mL, 0.173 mmol), triphenylphosphine (45.3 mg, 0.173 mmol) and piperizine (19.61 mg, 0.230 mmol) under argon. The mixture was heated with a microwave reactor at 45° C. for 0.5 h. Purification via MDAP then afforded the title compound (28 mg, 47.7% yield). LCMS: rt=3.02 min, [M+H+]=510
