Reaction Steps

Into an ice-cold solution of N-(benzyloxycarbonyl) glycine (26 g) and 2-isopropyl-4-imidazolidinone (16 g) in THF (260 ml), a solution of DCC (25.4 g) in THF (100 ml) was added dropwise. After stirring for 2 hours at 20° C., the precipitate was filtered off and the filtrate was evaporated to dryness. Crystallization of the residue from 2-propanol yielded 33.5 g of the title compound, m.p. 137°-139° C.
