Reaction Steps

To a mixture of quinuclidin-3-amine hydrochloride (1.06 g, 5.30 mmol) and polymer supported dimethylperhydro-1,3,2-diazaphosphorine (7.0 g, 15.4 mmol) in DMSO (50 mL) was added 5-fluoro-N-methyl-2-nitrobenzamide (Intermediate 3A) (1 g, 5.05 mmol) and reaction heated at 60° C. for 72 hours. The resin was removed by filtration and washed thoroughly with methanol and dichloromethane. The filtrate was purified using a 20 g SCX cartridge followed by trituration with dichloromethane/methanol/diethyl ether to afford N-methyl-2-nitro-5-(quinuclidin-3-ylamino)benzamide (0.41 g, 1.36 mmol).
