Procedure: 2-(tert-Butyl-dimethyl-silanyloxy)-propylamine (6.0 g, 31.6 mmol) was dissolved in DMF (60 mL). Diisopropylethylamine (5.5 mL, 31.6 mmol) and bromo-acetic acid tert-butyl ester (3.6 g, 18.6 mmol) was added. The reaction mixture was stirred at 50° C. for 16 h. The mixture was evaporated onto silica gel and and purified by column chromatography using a gradient, starting eluting with ethyl acetate/heptane 20:80 up to ethyl acetate/heptane 80:20. The product was isolated as an oil. Yield: 4.0 g, 71%. The mixture was evaporated onto silica gel purified by column chromatography starting eluting with ethyl acetate/heptane 20:80 up to ethyl acetate/heptane 80:20 The product was isolated as an oil

Procedure: tert-Butyl-chloro-dimethyl-silane (2.6 g 17 mmol) was dissolved in DCM (20 mL). 1-Amino-propan-2-ol (1.2 g, 16 mmol), triethylamine (2.2 mL, 16 mmol) and a catalytic amount of DMAP were added. The reaction mixture was stirred for 16 h. Water (10 mL) was added and the phases were separated. The aqueous phase was extracted with EtOAc (2×100 mL). The combined organic phases were dried over magnesium sulfate, filtered and the filtrate was evaporated in vacuo. The product was isolated as an oil. Yield: 2.4 g, 80%. the phases were separated The aqueous phase was extracted with EtOAc (2×100 mL) The combined organic phases were dried over magnesium sulfate filtered the filtrate was evaporated in vacuo The product was isolated as an oil
