Reaction Steps

Prepared as for 2-[4-(2-acetylamino-4-methyl-thiazole-5-sulfonylamino)-phenyl]-N-[6-amino-1-cyclopropylmethyl-3-(2-fluoro-benzyl)-2,4-dioxo-1,2,3,4-tetrahydro-pyrimidin-5-yl]-acetamide (example 10, step 1) except that the coupling was performed using 1 [3-(dimethylamino)propyl]-3-ethylcarbodiimide hydrochloride as the coupling reagent and [5-(5-chloro-1,3-dimethyl-1H-pyrazole-4-sulfonylamino)-pyridin-2-yl]-acetic acid and 5,6-diamino-3-(2-fluoro-benzyl)-1H-pyrimidine-2,4-dione were used as the coupling partners. Flash chromatography (Merck Silica gel 60, 230–400 mesh, 10/90 methanol/chloroform) afforded N-[6-amino-3-(2-fluoro-benzyl)-2,4-dioxo-1,2,3,4-tetrahydro-pyrimidin-5-yl]-2-[5-(5-chloro-1,3-dimethyl-1H-pyrazole-4-sulfonylamino)-pyridin-2-yl]-acetamide (42%) as an off white solid; LRMS for C29H29ClFN7O4S (M+H)+ at m/z=577/579.
