Reaction Steps

A solution of 1-(5-{5-[(5-chloropyridin-2-yl)sulfanyl]-2-(4-fluorophenyl)-1,3-oxazol-4-yl}pyrimidin-2-yl)ethanone (Example 73) (12 mg, 0.03 mmol) in THF (5 mL) was treated with methylmagnesium bromide (0.09 mL, 0.3 mmol, 3.0 M in THF) at it. Upon completion of the reaction as judged by TLC analysis, the solution was diluted with saturated aq NH4Cl solution and extracted with EtOAc. The organic layer was removed, dried over MgSO4, filtered and concentrated giving rise to an oil. The oil was purified on silica gel to afford the title compound (6.3 mg). LC/MS: m/e 443.0 (M+H)+. 1H NMR (500 MHz, Acetone-d6): δ 1.54 (s, 6H), 4.56 (s, 1H), 7.39 (m, 2H), 7.47 (d, J=8.5 Hz, 1H), 7.82 (m, 1H), 8.25 (m, 2H), 8.45 (d, J=2.5 Hz, 1H), 9.39 (s, 2H).
