Reaction Steps

To a solution of 1-(propylamino)propan-2-ol (8.00 g, 68.3 mmol), tert-butylchlorodimethylsilane (10.9 g, 72.4 mmol), and catalytic amount of DMAP in CH2Cl2 (68 mL) at 0° C. was added dropwise TEA (9.61 ml, 68.3 mmol). The reaction mixture was warmed to room temperature and stirred for 20 h. Additional 1 mL of TEA was added and stirred for additional 20 h. Water (60 mL) was added. The layers were separated. The aqueous layer was extracted with EtOAc (1×). The combined organic layers were washed with brine, dried over MgSO4, filtered, and concentrated under reduced pressure to give the crude material that was filtered again to afford quantitatively 2-(tert-butyldimethylsilyloxy)-N-propylpropan-1-amine that was used directly without further purification.
