Reaction Steps

Pd(PPh3)4 (15.13 mg, 0.013 mmol) is added to the solution of 2′-amino-6-bromo-1′,2,2-trimethylspiro[chroman-4,4′-imidazol]-5′(1′H)-one (44.15 mg, 0.13 mmol) and 3-cyanophenylboronic acid (19.25 mg, 0.13 mmol) in dimethyl-benzene (5 mL) and an aqueous solution of Na2CO3 (2 M, 0.24 mL). The mixture is heated at 90° C. in an oil bath overnight. The mixture is concentrated to give the crude product, which is purified by preparative TLC to give the desired product 3-(2′-amino-1′,2,2-trimethyl-5′-oxo-1′,5′-dihydrospiro[chroman-4,4′-imidazole]-6-yl)benzonitrile (10 mg, 15%).
