Reaction Steps

In a 50 mL round bottomed flask, 1-methyl-2-aminoethanol (500.0 mg, 6.66 mmol) and imidazole (498.8 mg, 7.326 mmol, 1.1 equiv.) were dissolved in THF (3 mL). The mixture was cooled down to −78° C. and then TESOTf (1.76 g, 6.66 mmol, 1.0 equiv.) was added at the same temperature. The mixture was allowed to warm to room temperature. After stirring for 1 h, water (30 mL) was added to the mixture and the whole was extracted with EtOAc (30 mL×3). Combined organic layers were washed with brine (30 mL) and dried over Na2SO4. The solvent was removed under a reduced pressure to give the O-silylated aminoalcohol as a colorless oil (2-(triethylsilyloxy)propan-1-amine, 2.34 g). Obtained product was immediately used for the subsequent step.
