Reaction Steps
Compound 52C was prepared following the procedure as described for the synthesis of compound 52A (see Scheme 10) using pentanol (25 ml) and 3-[4-iodo-1-(2-trimethylsilanyl-ethoxymethyl)-1H-pyrazol-3-yl]-1-azabicyclo[2.2.2]octane (50), (2 g, 4.61 mmol). Work-up and flash chromatography (gradient EtOH to EtOH/triethylamine 300/1) followed by a second flash chromatography (EtOH/ethyl acetate/triethylamine 25/75/1) afforded compound 51C as an oil (0.46 g, 15%). LCMS (method B); Rt: 3.30 min, ([M+H]+=394).
