Reaction Steps

To a solution of (S)-1-amino-3-{2-ethyl-4-[5-(4-isobutyl-6-methyl-pyridin-2-yl)-[1,2,4]oxadiazol-3-yl]-6-methyl-phenoxy}-propan-2-ol (36 mg, 86 μmol), HOBt (14 mg, 103 μmol) and glycolic acid (8 mg, 103 μmol) in THF (3 mL), EDC HCl (20 mg, 103 μmol) is added. The mixture is stirred at rt for 18 h before it is diluted with sat. aq. NaHCO3-solution and extracted twice with EA. The combined org. extracts are dried over MgSO4, filtered and concentrated. The crude product is purified by prep. TLC using DCM containing 11% of methanol to give the title compound (36 mg) as a pale yellow oil; LC-MS: tR=0.98 min, [M+H]+=483.21; 1H NMR (CDCl3): δ 0.98 (d, J=6.3 Hz, 6H), 1.31 (t, J=7.5 Hz, 3H), 1.97-2.08 (m, 1H), 2.38 (s, 3H), 2.59 (d, J=6.8 Hz, 2H), 2.69-2.78 (m, 5H), 2.81 (s br, 1H), 3.42 (s br, 1H). 3.48-3.57 (m, 2H), 3.74-3.93 (m, 2H), 4.17-4.25 (m, 3H), 7.05 (s br, 1H), 7.19 (s, 1H), 7.93 (s, 1H), 7.94 (s, 2H).
