Reaction Steps

2-(4-Methylphenethyloxy)-5-nitropyridine (3.7 g) and 1.7 g of 5% palladium charcoal were suspended in 37 ml of ethanol, and catalytic reduction was carried out until 1.1 liters of hydrogen were absorbed. After removal of the catalyst by filtration, the solvent was distilled out under reduced pressure. The crystals were collected on a glass filter and washed with ether to give 3.1 g of 2-(4-methylphenethyloxy)-5-aminopyridine as yellow crystals. Yield, 84.9%. M.P., 64.5°-65° C.
