실험 절차

To a solution of thiazole-4-methanol (79 mg) in THF (1 mL) at 0° C. under argon was added 1M lithium bis(trimethylsilyl)amide in THF (0.35 mL). After 30 minutes N-{5-[(cyclopropylamino)carbonyl]-2-methylphenyl}-2-(methylsulfonyl)pyrimidine-5-carboxamide (127 mg, 0.34 mmol) in THF (3 mL) was added and the reaction warmed to room temperature and stiired for 5 hours. The reaction mixture was partitioned between ethyl acetate and water, the organic phases washed with brine, dried (Na2SO4) and concentrated. The residue was purified by flash chromatography on a 12 g silica cartridge eluting with a gradient of 0 to 5% Methanol/DCM to give the title compound as a solid (31 mg, 23%); NMR Spectrum: (DMSOd6) 0.56 (m, 2H), 0.69 (m, 2H), 2.29 (s, 3H), 2.85 (m, 1H), 5.63 (s, 2H), 7.36, (d, 1H) 7.67 (dd, 1H), 7.83 (dd, 2H), 8.49 (d, 1H), 9.14 (m, 2H), 10.14 (s, 1H); Mass Spectrum: M+H+ 410.
