Reaction Steps

420 mg (1.88 mmol) of 5-nitro-1-benzothiophene-2-carboxylic acid, 374.7 mg (1.88 mmol) of R-3-aminoquinuclidine dihydrochloride, 858.6 mg (2.26 mmol) of HATU, 875.5 mg (6.78 mmol) of N,N-diisopropylethylamine and 2.0 ml of DMF are reacted according to the general procedure (variant B). The resulting precipitate is suspended in 1N HCl in diethyl ether, filtered off, washed twice with dichloromethane and dried under high vacuum. 523 mg (75.6% of theory) of the title compound are obtained.
