Procedure:
To a stirred solution of 3-[2-(tert-butoxycarbonyl-pyridin-4-yl-amino)-ethoxy]-5-chloro-benzoic acid (0.104 g), TBTU (0.128 g), and HOBt (0.061 g) in DMF (1 ml) was added DIPEA (0.139 ml) and 5-(2-isopropylamino-ethyl)-[1,2,4]oxadiazol-3-ylamine (0.05 g). The reaction mixture was stirred at room temperature for 10 days, then silica was added and the solvent removed by evaporation at reduced pressure. The resulting silica was loaded onto the top of a column of silica which was then eluted with a gradient [cyclohexane:ethyl acetate (1:1 v/v) to neat ethyl acetate to ethyl acetate:methanol (9:1 v/v)]. Concentration of the required fraction at reduced pressure furnished the title compound as a yellow glass (0.069 g).

Procedure:
4-(4-fluorobenzyloxy)-3-isobutylbenzoic acid (16.5 g) was dissolved in a mixture of chloroform (150 ml) and triethylamine (15.3 ml). To this mixture was added diphenylphosphinic chloride (11.5 ml) while being cooled with ice. After being stirred for 40 minutes, the mixture, with 1-isobutylpiperazine (7.83 g) added thereto, was stirred for 1.5 hours at room temperature. This reaction mixture was washed with saturated sodium hydrogencarbonate solution and saturated brine successively, dried over sodium sulfate anhydride, and then concentrated under a vacuum. Thus obtained residue was purified by silica gel column chromatography (chloroform: methanol=50:1) and the resulting solid was recrystallized (from n-hexane), thereby yielding 19.6 g of the aimed compound.
