Reaction Steps

A mixture of [4-(6-bromo-1H-indazol-3-yl)-piperidin-1-yl]-acetic acid tert butyl ester (1.34 g, 3.40 mmol), 4-vinyl-piperidine-1-carboxylic acid tert-butyl ester (0.75 g, 3.57 mmol), triethylamine (1.4 ml, 10.2 mmol), palladium (ii) acetate (0.050 g, 0.22 mmol) and tri(o-tolyl)phosphine (0.210 g, 0.6 mmol) in DMF (60 ml) was stirred at 120° under nitrogen for 16 h. The mixture was evaporated in vacuo and purified by flash chromatography on silica gel (Merck 9385), eluant ethyl acetate:cyclohexane:triethylamine (50:50:2→100:0:2), to give the title compound as a yellow solid (1.18 g, 66%).
