Under protection of nitrogen, 2-aminophenylethanol (1.30 g, 9.5 mmol) was dissolved in anhydrous tetrahydrofuran (100 mL), the resulting solution was slowly added dropwise to a suspension of sodium hydride (60%, 0.42 g, 10.4 mmol) in anhydrous tetrahydrofuran (20 mL), the mixture was stirred for 15 min at room temperature, and added with tert-butyldiphenylchlorosilane (2.86 g, 10.4 mmol), and stirred for 20 hrs at room temperature. The reaction system was added with water, and extracted with methyl tert-butyl ester. The extracts were combined, dried with anhydrous sodium sulfate, and concentrated under reduced pressure, to obtain a brown oil (3.75 g).
