Conditions

Temperature: 100 °C

Procedure

(3R*,5S*)-1-(tert-Butoxycarbonyl)-5-[({2-tert-butyl-4-[(2-furylmethyl)amino]pyrimidin-5-yl}carbonyl)(isobutyl)amino]piperidine-3-carboxylic acid (120 mg) and 5-methyl-1H-tetrazole (22 mg) were suspended in toluene (3 ml), DCC (60 mg) was added and the mixture was stirred at 100° C. for 14 hr. The reaction mixture was cooled to room temperature, and concentrated under reduced pressure. The residue was subjected to silica gel column chromatography, and the fraction eluted with ethyl acetate-hexane (5:95-75:25) was concentrated under reduced pressure to give the object compound (74.7 mg).
