Reaction Steps

Following General Procedure C and using N-(3-nitrophenylacetyl)-L-alanine (from Example D11 above) and 4-[(S)-2-amino-3-tert-butoxybutyryl]-morpholine (prepared from N-BOC-O-tert-butyl-L-threonine (Sigma) and morpholine (Aldrich) using General Procedure M, followed by removal of the BOC-group using General Procedure P), the title compound was prepared as a solid. The reaction was monitored by tlc (Rf=0.1 in 95:5 CHCl3/MeOH) and the product was purified by silica gel chromatography using 96:4 CHCl3/MeOH as the eluent.
