Procedure

A suspension of tert-butyl 2-amino-6-[2,6-bis(benzyloxy)phenyl]-4-[1-(tertbutoxycarbonyl)-3-piperidinyl]nicotinate (1.00 g, 1.052 mmol) and 10% Paradium-carbon (0.500 g) in 20 mL of ethyl acetate was stirred at room temperature under a hydrogen atmosphere (1 atm) overnight. After paradium carbon was removed by filtration on Celite®, the filtrate was concentrated under reduced pressure to give tertbutyl 2-amino-4-[1-(tert-butoxycarbonyl)-3-piperidinyl]-6-(2,6-dihydroxyphenyl)nicotinate as a brown oil. (0.710 g, yield; 97%)
