Reaction Steps
KH2PO4 (712 mg, 5.23 mmol) and NaCN (251 mg, 5.12 mmol) were added to a solution of 2-(4-fluorophenyl)oxazole-4-carbaldehyde (500 mg, 2.62 mmol) in DMF-H2O (10 mL, 4:6, v/v). The resulting reaction mixture was stirred at room temperature for 1 h, then diluted with water and extracted with EtOAc. The combined extracts were washed with H2O and brine, dried over anhydrous Na2SO4, and concentrated under reduced pressure to afford 2-(2-(4-fluorophenyl)oxazol-4-yl)-2-hydroxyacetonitrile (500 mg, yield 87%). 1H NMR (400 MHz, CDCl3) δ 8.07-8.02 (m, 2H), 7.88 (s, 1H), 7.20-7.16 (t, J=8.8 Hz, 2H), 5.62 (s, 1H), 4.38 (br s, 1H). MS (ESI) m/z: Calculated for C11H7FN2O2: 218.05. found: 218.8 (M+H)+.
