実験手順

30.95 g (347 mmol) of 2-amino-2-methyl-1-propanol was weighed into a 500 mL Erlenmeyer flask fitted with a stir bar and septum. Added 200 mL CH2Cl2. Established and maintained nitrogen atmosphere. Stirred the solution in an ice/water bath. Added 34 mL (174 mmol) of 4-tert-butylbenzoyl chloride dropwise over 30 min. A white precipitate formed. Stirred at room temperature overnight. Removed the solids by filtration and washed with CH2Cl2. Removed the solvent from the filtrate on rotavap and dried at 60°/4 torr to obtain 45.79 g of the title compound as a light yellow resin. MS (ESI) 248 (M−H)31 .
