Procedure

To a solution of 2-pyridinylmethanol (258 μl, 2.67 mmol) in THF (50 mL) cooled in ice bath to 0° C. was added dropwise lithium hexamethyldisilazide (1M solution in THF, 2.67 mL, 2.67 mmol) and the resulting mixture stirred for 30 minutes at 0° C. N-{5-[(cyclopropylamino)carbonyl]-2-methylphenyl}-2-(methylsulfonyl)pyrimidine-5-carboxamide (1 g, 2.67 mmol) was added and the resulting mixture stirred for 16 h at room temperature. The reaction mixture was concentrated under reduced pressure and the residue partitioned between water and DCM. Concentration of the organic phase under reduced pressure and crystallisation from acetonitrile gave the title compound as a colourless solid (132 mg, 12%); NMR Spectrum: (DMSOd6) 0.57 (m, 2H), 0.69 (m, 2H), 2.30 (s, 3H), 2.86 (m, 1H), 5.61 (s, 2H), 7.36 (m, 2H), 7.49 (m, 1H), 7.66 (m, 1H), 7.85 (m, 2H), 8.38 (m, 1H), 8.58 (m, 1H), 9.16 (s, 2H), 10.16 (s, 1H); Mass Spectrum: M+H+ 404.
