Monobenzone → 4-(4-Benzyloxy-phenoxy)-2-chloro-pyrimidine

Participants

Reaction Steps

To a stirred RT slurry of NaH (0.5 g of 60% oil dispersion, 12.6 mmol) in 15 mL DMF was added 4-benzyloxyphenol (2.40 g, 12.0 mmol). The mixture was stirred for 10 min before 2,4-dichloropyrimidine (1.79 g, 12.0 mmol) was added. A mild exotherm occurred. The reaction was stirred for 2 h and quenched with saturated aqueous NaHCO3. The reaction was diluted with EtOAc, the layers were separated, and the organic layer was washed twice with 2 N NaOH, once with brine, then dried over Na2SO4. The organic layer was filtered and concentrated in vacuo to yield crude title compound contaminated with minor impurities by H-NMR. MS (MH+)=NA; Calc'd 312.76 for C17H13ClN2O2.
