Reaction Steps

A mixture of 7-({2-[(4-methoxybenzyl)amino]-1-oxidopyridin-4-yl}oxy)-1,2,3,4-tetrahydronaphthalene-2-carboxylic acid (21.1 g, 0.0502 mol), cyclohexene (100 mL, 0.9 mol) and Pd (10% on Carbon, 4.5 g) in isopropyl alcohol (400 mL, 5 mol) was heated at 85° C. overnight. Additional catalyst (2.5 g) and cyclohexene (30 mL) were added. The mixture was heated at 90° C. overnight and then filtered. The filtrate was concentrated to give 7-({2-[(4-methoxybenzyl)amino]pyridin-4-yl}oxy)-1,2,3,4-tetrahydronaphthalene-2-carboxylic acid which was used in the next step without purification.
