Procedure

Prepared by a method analogous to that described in Example 1 from (R)-N-(1-azabicyclo[2.2.2]oct-3-yl)(5-bromofuran-2-carboxamide) and 3-(N-acetylamino)phenylboronic acid, using tetrakis(triphenylphosphine)palladium (0) and sodium carbonate in a mixture of 1,2-dimethoxyethane and water. The compound was purified by reverse phase HPLC on a Waters Bondapak® C18 column using a gradient of acetonitrile and 0.1% aqueous trifluoroacetic acid as the eluent. The product-containing fractions were then evaporated and the residue dissolved in methanol. Excess hydrogen chloride solution (1M in diethyl ether) was added and the solution was evaporated. Recrystallisation from methanol/diethyl ether gave the hydrochloride salt of the title compound as a yellow solid; MS (ES+) 354 (MH+).
