Procedure
4-(2,4-Dimethoxy-phenyl)-pyridine (6.9 g) is dissolved in a mixture of Ethanol (140 ml) and conc hydrochloric acid (3.5 ml). PtO2 (0.7 g) is added and the mixture is stirred under hydrogen atmosphere for 8 hours. The catalyst is filtered off and the solution is evaporated to dryness. MS-APCI+ (M+H)+=222
