46% | With 1-methyl-pyrrolidin-2-one; iron(III)-acetylacetonate In tetrahydrofuran at 20℃; for 3 h; | To a solution of 4,6-dichloropyrimidine (1.0 g, 6.71 mmol) in tetrahydrofuran (30 mL) was added l-methyl-2-pyrrolidinone (3.2 mL, 6.71 mmol), iron(III) acetylacetonate (0.119 g, 0.336 mmol) and methylmagnesium bromide (2.237 mL, 6.71 mmol). The reaction mixture was stirred at RT for 3 h, then it was quenched with water and extracted with ethyl acetate (100 mL). The organic layer was separated out and concentrated under reduced pressure. The residue was purified by silica gel chromatography (20percent ethyl acetate-hexane) to afford 4-chloro-6- methylpyrimidine (0.6 g, 3.08 mmol, 46percent yield) as a colorless gummy liquid. LCMS (ESI) m/e 129.0 [(M+H)+, calcd for C5H6C1N2 129.0]; LC/MS retention time (method D): /R = 1.36 min. |
