Procedure

A mixture of 3,5-di-fluoro-phenyl acetic acid (51.6 mg, 0.3 mmol), 2-amino-pentanoic acid (5-tert-butyl-[1,3,4]thiadiazol-2-yl)-amide (88 mg, 0.3 mmol), HBOT (43 mg, 0.315 mmol), EDC HCl (69 mg, 0.36 mmol.) and triethylamine (0.17 ml) in methylene chloride was stirred at room temperature until product formation or disappearance of starting material. The mixture was quenched with water and extracted with methylene chloride. The organic layer was separated, washed with dilute HCl, brine, dried over sodium sulfate and the solvent was removed at reduced pressure to provide the title compound as a cude oil. The oil was purified by Shimadzu HPLC to provide the title compound as a white solid (56 mg), LC-MS M+1=411.2, 1H NMR(CDCL3) 8.7 (d,1H,NH), 6.73(m,2H), 6.6(m,1H), 4.7(m,1H), 3.5(Abq, 2H), 1.6-1.9(m,2H), 1.3-1.6(m,2H), 1.5(s,9H), 0.92(t,3H) ppm.
