反応手順
1 g of 4-(4-tert-butylanilino)-3-methoxy-2-methylpyridine in 20 ml of methanol, 3.7 ml of 2N HCl and 1.3 ml of water are hydrogenated at room temperature and normal pressure until absorption of hydrogen has ended using 1 g of rhodium on alumina (5% strength). After filtering and concentrating 1 g of syrup remains=100% isomer mixture.
