Reaction Steps

A suspension of 4-bromomethylbenzonitrile (10 g, 0.054 mol), 9-oxa-3,7-diaza-bicyclo[3.3.1]nonane-3-carboxylic acid tert-butyl ester (11.5 g, 0.0439 mol; see WO 01/28992) and dry K2CO3 (21.2 g, 0.153 mol) in 200 ml of dry acetonitrile was stirred at 60° C. overnight under N2 atmosphere. The reaction mixture was filtered through celite and filtrate was concentrated under reduced pressure. The residue was purified by column chromatography over silica gel using 10% ethyl acetate in petroleum ether as eluent to yield (10 g) of the sub-title compound as colorless liquid.
