Reaction Steps
35 mg (0.20 mmol) of thieno[3,2-b]pyridine-2-carboxylic acid, 58.3 mg (0.29 mmol) of R-3-aminoquinuclidine dihydrochloride, 111.4 mg (0.29 mmol) of HATU, 138.8 mg (1.07 mmol) of N,N-diisopropylethylamine and 1.5 ml of DMF are reacted according to the general procedure (variant A). The reaction mixture is purified by preparative HPLC and then subjected to fine purification on silica gel 60 (mobile phase: dichloromethane/methanol/ammonia 90:9:1). 44 mg (78% of theory) of the title compound are isolated.
