Reaction Steps
Prepared by the method described for example 26 from 1,2,3,4-tetrahydro-5H-[1]benzopyrano[3,4-c]pyridin-5-one (5.14 g, 0.025 moles), triethylamine (3.8 g, 0.027 moles), and 1-chloro-2-propanone (2.5 g, 0.027 moles). Recrystallization from ethanol gave the produce (3.8 g) mp 128°-130° C.
