Participants

Reaction Steps

To a solution of crude 1-amino-3-{2-ethyl-4-[3-(2-isopropylamino-6-methyl-pyrimidin-4-yl)-[1,2,4]oxadiazol-5-yl]-6-methyl-phenoxy}-propan-2-ol (43 mg, 97 μmol) in DMF, glycolic acid (11 mg, 146 μmol), HOBt (20 mg, 146 μmol), and EDC hydrochloride (28 mg, 146 μmol) are added. The mixture is stirred at rt for 18 h before it is diluted with sat. aq. NaHCO3 and extracted twice with EtOAc. The combined org. extracts are dried over MgSO4, filtered and concentrated. The crude product is purified by prep. TLC plates with DCM containing 10% of 7M NH3 in MeOH to give (S)—N-(3-{2-ethyl-4-[3-(2-isopropylamino-6-methyl-pyrimidin-4-yl)-[1,2,4]oxadiazol-5-yl]-6-methyl-phenoxy}-2-hydroxy-propyl)-2-hydroxy-acetamide (21 mg) as a white solid; LC-MS: tR=0.85 min; [M+H]+=485.14; 1H NMR (CDCl3): δ 1.29 (m, 9H), 2.35 (m, 3H), 2.46 (s, 3H), 2.72 (q, J=7.5 Hz, 2H), 3.52 (m, 1H), 3.76 (m, 1H), 3.87 (m, 3H), 4.20 (m, 3H), 4.31 (m, 1H), 5.31 (m, 1H), 7.22 (s, 1H), 7.25 (t, J=6.0 Hz, 1H), 7.89 (s, 1H), 7.91 (s, 1H).
