Reaction Steps

7-Chloro-3-(1,2,3,6-tetrahydropyridin-4-yl)-1H-indole (2.0 g, 8.62 mmol) and 0.5 g of platinum oxide were added to 100 mL of ethanol and the mixture was shaken under about 50 psi hydrogen at about ambient temperature for about a day. The mixture was filtered and the filtrate concentrated to yield a solid comprising the desired product. Yield 1.64 g (81%) as a yellow solid. FDMS m/e=234 (M+).
