実験手順

To the solution of N-(2-((6-(3-(2,6-dichloro-3,5-dimethoxyphenyl)-1-methylureido)pyrimidin-4-yl)amino)-5-(piperazin-1-yl)phenyl)acrylamide 2,2,2-trifluoroacetate (Procedure 2L, Example 157) (30 g, 0.042 mmol) in THF (1.0 ml) and MeOH (1.0 ml) was added tert-butyl(2-oxoethyl)carbamate (13 g, 0.08 mmol). The reaction mixture was stirred at room temperature for 10 minutes. Sodium cyanoborohydride (7.0 g, 0.12 mmol) was added and the reaction mixture was stirred at room temperature over night. Solvent was evaporated and saturated NaHCO3 solution was added. The mixture was extracted three times with DCM. Combined organic layer was dried over Na2SO4 and evaporated. The remaining material was purified by flash chromatography on silica eluting with 0% to 15% MeOH in DCM to afford the title compound (17 mg, yield: 54%) ESI-MS: 744 [M+H]+.
