Reaction Steps
Triethylamine (32.4 ml) was added to N-tert.-butyloxycarbonyl β-alanine (40 g) in N,N'-dimethylformamide at room temperature under a nitrogen atmosphere in a 1 l round bottom flask. The solution was stirred 15 minutes and chloromethyl pivalate (36.6 g) [M. Rasmussen & N. J. Leonard, J. Amer. Chem. Soc., 89, 5439 (1967)] was added dropwise at 0° C. The solution was stirred at room temperature overnight. The mixture was then diluted with ethyl acetate, filtered, washed with water, then brine, and evaporated to give 70 g crude material which was chromatographed (silica gel) eluting with 15% ethyl acetate-hexane to give 62.5 g of product.
