Reaction Steps
2,3,4a,5-Tetrahydro-9-methoxy-4-propyl-4H-[1]-benzopyrano[3,4-b]pyridin-2-one is heated with lithium aluminum hydride in ether. The resulting product is hydrogenated in ethanol in the presence of 10% palladium on carbon catalyst to give 9-methoxy-4-propyl-1,2,3,4a,5,10b-hexahydro-4H-[1]-benzopyrano[3,4-b]pyridine.
