A mixture of 4-[5-(2-cyclopentyl-6-methoxy-pyridin-4-yl)-[1,2,4]oxadiazol-3-yl]-2-ethyl-6-methyl-phenol (250 mg, 659 μmol), (R)-3-chloro-1,2-propanediol (609 mg, 6.59 mmol) in isopropanol (8 mL) and 3 M aq. NaOH (2 mL) is stirred at 60° C. for 15 h. The mixture is diluted with EA and washed with brine, 1 M aq. NaOH and again with brine. The org. extract is dried over Na2SO4, filtered and concentrated. The crude product is purified on prep. TLC plates using DCM containing 10% of methanol to give the title compound (297 mg) as a pale yellow oil; LC-MS**: tR=0.87 min, [M+H]+=454.26.
