Participants

Reaction Steps

To a solution of 2-ethyl-4-[5-(4-isobutyl-6-methyl-pyridin-2-yl)-[1,2,4]oxadiazol-3-yl]-6-methyl-phenol (41 mg, 0.116 mmol) in isopropanol (3 mL) and 3 N aq. NaOH (0.4 mL), (S)-3-chloro-1,2-propanediol (66 mg, 0.577 mmol) is added. The mixture is stirred at 65° C. for 16 h before another portion of (S)-3-chloro-1,2-propanediol (66 mg, 0.577 mmol) and 3 N aq. NaOH (0.4 mL) is added. Stirring is continued at 65° C. for 24 h. The mixture is cooled to rt, diluted with water, and repeatedly extracted with diethyl ether. The combined org. extracts are dried over MgSO4, filtered and concentrated. The crude product is purified on prep. TLC using DCM:methanol 9:1 to give the title compound (16 mg) as a colourless oil; LC-MS: tR=1.02 min, [M+H]+=426.17.
