Versuchsvorschrift

Pd(PPh3)2Cl2 (10 mg, 0.014 mmol) in a 10 mL tube under Ar was treated sequentially with 2′-amino-6-bromo-1′-(cyclohexylmethyl)-2-phenylspiro[chroman-4,4′-imidazol]-5′(1′H)-one (30 mg, 0.064 mmol) in 1,4-dioxane (1.5 mL), Cs2CO3 (2 N, 0.5 mL) and 3-cyanophenylboronic acid (19 mg, 0.128 mmol). The mixture was heated at 120° C. under microwave reactor for 0.5 h. The reaction mixture was concentrated in vacuo to give the residue, which was purified by preparative TLC followed by preparative HPLC to give pure 3-(2′-amino-1′-(cyclohexylmethyl)-5′-oxo-2-phenyl-1′,5′-dihydrospiro[chroman-4,4′-imidazole]-6-yl)benzonitrile (9.74 mg, 31%). 1H-NMR (MeOD): 1.02 (m, 5H), 1.62 (m, 6H), 2.03 (m, 1H), 2.24 (m, 1H), 3.30 (m, 1H), 3.44 (m, 1H), 5.91 (m, 1H), 6.97 (m, 1H), 7.16 (m, 1H), 7.25 (m, 1H), 7.35 (m, 3H), 7.46 (m, 2H), 7.56 (m, 1H), 7.71 (m, 2H)
