(x) 4-{2-[3-(1-tert-Butoxycarbonylmethyl-piperidin-4-yl)-1-(4-fluoro-benzyl)-1H-indazol-6-yl]-(E)-vinyl}-piperidine-1-carboxylic acid tert-butyl ester A stirred mixture of {4-[6-bromo-1-(4-fluoro-benzyl)-1H-indazol-3-yl]-piperidin-1-yl}-acetic acid tert-butyl ester (286 mg, 0.57 mmol), 4-vinyl-piperidine-1-carboxylic acid tert-butyl ester (120 mg, 0.57 mmol), lithium chloride (24 mg, 0.57 mmol), triethylamine (0.24 ml, 1.71 mmol), palladium (II) acetate (8 mg 0.03 mmol), tri-o-tolylphosphine (35 mg, 0.11 mmol), and DMF (5 ml) was heated at 105 (oil-bath temperature) under nitrogen for 18 h. When cool, the mixture was evaporated in vacuo, treated with aqueous saturated sodium bicarbonate (20 ml), and extracted with ethyl acetate (2*20 ml). The combined, dried (Na2 SO4) organic extracts were evaporated, and the residue purified by flash chromatography over silica gel (Merck 9385). Elution with ethyl acetate –cyclohexane (1:2) afforded impure fractions and pure fractions (I). The impure fractions were purified by flash chromatography over silica gel (Merck-9385) eluding with ethyl acetate–cyclohexane (gradient 1:4 to 1:2) to give pure fractions (II). The pure fractions (I) and (II) were combined to give the title compound as a pale yellow oil (195 mg).
