Reaction Steps
Prepared by the method described for Example 13 from 9-chloro-1,2,3,4-tetrahydro-8-methyl-5H-[1]benzopyrano[3,4-c]pyridin-5-one (2.0 g, 0.008 moles), 0.008 moles), triethylamine (2.3 ml, 0.017 moles), and 3-(2-chloroethyl)-3-azabicyclo[3.2.2]nonane hydrochloride (1.8 g, 0.008 moles). Recrystallization from ethanol gave the product (2.0 g) as the hemihydrochloride, mp 255° C. (dec).
