Reaction Steps

Following General Procedure I above using N-(3,5-difluorophenylacetyl)-L-alanine (Example B) and 3-amino-1-methyl-2-indolinone monohydrochloride (Example 5-J), the title compound, as a ˜1:1 diastereomeric mixture at C3 of the indolinone, was prepared as a white solid having a decomposition point of 215-220° C. Purification was by flash chromatography eluting with 3:1 CH2Cl2/EtOAc gradient to straight EtOAc followed by recrystalization from CHCl3. Rf=0.16 and 0.22 (EtOAc).
