実験手順: To a suspension of 4-bromo-3-methylbenzoic acid (25 g) and 4-(dimethylamino)pyridine (“DMAP”, 2.1 g) in CH2Cl2 (320 mL) was added N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide (“EDC”, 22.4 g) portionwise. Then, (aminomethyl)trimethylsilane (8.6 mL) was added, while cooling to keep the internal temperature below 20° C. The reaction was stirred at room temperature overnight. Water was added under vigorous stirring, and the layers were separated. The aqueous layer was extracted twice with CH2Cl2, and the combined organic phase dried (Na2SO4), and filtered over silica gel using CH2Cl2 and methyl tert-butyl ether (MTBE) to afford the title compound (32.8 g, 94%). while cooling the internal temperature below 20° C the layers were separated The aqueous layer was extracted twice with CH2Cl2 the combined organic phase dried (Na2SO4) filtered over silica gel

実験手順: To a suspension of 4-bromo-3-chlorobenzoic acid (25.00 g, 106.2 mmol) in CH2Cl2 (320 mL) was added N,N-dimethyl aminopyridine (1.95 g), followed by N-ethyl-N-dimethylamine propylcarbodiimide hydrochloride (22.39 g) in small portions. After 30 min at room temperature, aminomethyl trimethylsilane (11.2 g, 7.87 mL, 108 mmol) was added while maintaining the temperature at 20° C. After stirring over night, water was added and the organic layer was separated. The aqueous layer was extracted twice with CH2Cl2 and the combined organic phases were dried and evaporated in vacuum. The residue was purified by flash chromatography on silica gel to give the title compound (34.00 g, 100%). the organic layer was separated The aqueous layer was extracted twice with CH2Cl2 the combined organic phases were dried evaporated in vacuum The residue was purified by flash chromatography on silica gel

実験手順: To a solution of (aminomethyl)trimethylsilane (Fluka) (1.03 g, 10 mmol) in dichloromethane (20 mL) was added 3,3-dimethyl-butyraldehyde (Aldrich) (1.0 g, 10 mmol). The reaction mixture was stirred at room temperature for 3 h. Water was added. The organic layer was separated, washed with brine, dried over MgSO4, and concentrated to give [3,3-dimethyl-but-(E)-ylidene]-trimethylsilanylmethyl-amine as a colorless oil (1.8 g, 97%). The organic layer was separated washed with brine dried over MgSO4 concentrated
