NaOH (1 mL) followed by (S)-3-chloro-propane-1,2-diol (67 μL, 0.85 mmol) is added. The reaction mixture is stirred at rt for 15 h, and is then diluted with EtOAc and washed with 1M aq. NaOH followed by brine. The org. solution is dried over Na2SO4, filtered and evaporated to give 3-{2-ethyl-4-[5-(2-isopropylamino-6-methyl-pyrimidin-4-yl)-oxazol-2-yl]-6-methyl-phenoxy}-propane-1,2-diol (9 mg) as a yellow solid; LC-MS: tR=0.79 min, [M+H]+=426.80.
