Reaction Steps
A suspension of 2,2′-azanediyldiethanol (7.3 ml, 76.09 mmol), sodium carbonate (18.33 g, 172.94 mmol), acetone (125 ml), and water (125 ml) at 0° C. was treated dropwise over a 15 minute period with Cbz-Cl (10.25 ml, 69.17 mmol). The suspension was stirred an additional 3 hours at 0° C. The suspension was diluted with water (500 ml) and extracted with CHCl3 (2×250 ml). The combined organic extracts were dried over sodium sulfate, filtered and concentrated under reduced pressure. The concentrate was purified by column chromatography (ISCO, eluting with MeOH/DCM, 0→10% over 40 minutes) to give the title compound (12.5 g, yield: 76%).
