A solution of (2,4-bis-benzyloxy-5-isopropenyl-phenyl)-(5-bromo-1,3-dihydro-isoindol-2-yl)-methanone (200 mg; 0.36 mmol) and 1-methyl-4-(piperidin-4-yl)piperazine (80 mg; 1.2 equiv.) in toluene (5 ml) was treated with (2-biphenyl)-di-tert-butylphosphine (6 mg; 5 mol %), tris(dibenzylidene)palladium(0) (10 mg; 2.5 mol %) and sodium tert-butoxide (50 mg; 1.4 equiv.) then heated at 120° C. for 30 minutes in a CEM explorer microwave synthesiser. The reaction mixture was diluted with DCM, washed with brine, dried (MgSO4) and evaporated. Purification by flash column chromatography (Biotage SP4-25 S, 25 ml/min) eluting with DMAW 240-120-90 followed by evaporation of product containing fractions gave 105 mg of (2,4-bis-benzyloxy-5-isopropenyl-phenyl)-{5-[4-(4-methyl-piperazin-1-yl)-piperidin-1-yl]-1,3-dihydro-isoindol-2-yl}-methanone as the acetic acid salt.
