tert-butyl-dimethyl-(3-nitropropoxy)silane

反応条件: temp:60.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a solution of 5-ethynyl-N2-(3-fluorophenyl)-N4-propylpyrimidine-2,4-diamine (S2, 30 mg) and tert-butyldimethyl(3-nitropropyloxy)silane (S3, 146 mg) synthesized according to the method described in Journal of Medicinal Chemistry, 2011, 54, pp. 7280-7288 in toluene (1 mL), phenyl isocyanate (36 μL) and triethylamine (46 μL) were added at room temperature, and the mixture was stirred at 60° C. for 4 hours and 40 minutes. To the reaction mixture, phenyl isocyanate (36 μL) and triethylamine (46 μL) were added, and the mixture was further stirred at 60° C. for 6 hours. The reaction mixture was cooled to room temperature, and then water and ethyl acetate were added to the reaction mixture. The organic layer was separated, and dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure to obtain 5-(3-(2-((tert-butyldimethylsilyl)oxy)ethyl)isoxazol-5-yl)-N2-(3-fluorophenyl)-N4-propylpyrimidine-2,4-diamine (S4, 22 mg). the mixture was further stirred at 60° C. for 6 hours The reaction mixture was cooled to room temperature The organic layer was separated dried over anhydrous magnesium sulfate the solvent was evaporated under reduced pressure
