Reaction Conditions

Reaction Steps

A solution of methyl 5-(pyrimidin-4-yl)oxazole-4-carboxylate (179 mg, 0.80 mmol) in THF/H2O (1:1, 6 mL) was treated with LiOH (60 mg, 1.43 mmol) at 0° C. The reaction mixture was stirred at 0° C. for 15 min, then diluted with EtOAc and 1N aq. HCl-solution was added (to reach pH=1). The layers were separated and the aq. layer extracted with EtOAc (2×), EtOAc/MeOH 4:1 then DCM/MeOH 4:1. The combined organic extracts were dried (Na2SO4), filtered and concentrated in vacuo to obtain the title compound as a solid which was used without further purification. LC-MS conditions A: tR=0.56 min, [M+H]+=192.47.
