Participants

Reaction Steps

A solution of phthalic acid (0.7223 g, 0.00435 mol) in ethyl acetate (10 ml) was added to a solution of (S)-1-(4-amino-3-methylphenyl)methyl-N,N-dimethyl-5-diphenylacetyl-4,5,6,7-tetrahydro-1H-imidazo-[4,5-c]pyridine-6-carboxamide (II-2) (2.0077 g, 0.00396 mol) in ethyl acetate (30 ml) with stirring at room temperature. The mixture was stirred at room temperature for 23 hours, followed by filtration of the reaction mixture. The resulting white solid was washed with ethyl acetate (about 20 ml) and dried to obtain the objective compound (I-2, Compound No. 2) (2.4107 g; yield: 93.0%). MS 637 (EI): (M-18).
