Procedure

To a stirred solution of 3-aminopropan-1-ol (2 g, 20 mmol) in DCM (10 mL), imidazole (79 mmol, 3 equiv.) was added and stirred at room temperature for 10 min. Reaction mixture was cooled to 0° C., t-butyl dimethyl silyl chloride (30 mmol, 1.2 equiv.) was added in portions and stirred the reaction mixture overnight at room temperature. Diluted the reaction mixture using DCM, the DCM layer was washed with water. The organic layer was collected, dried over Na2SO4, filtered and concentrated. ELSD method LC/MS: Retention time: 1.5 min; (ES-API), m/z 189.7 (M+H).
