Related Products of 52798-01-3,Some common heterocyclic compound, 52798-01-3, name is Methyl (4-cyanophenyl)acetate, molecular formula is C10H9NO2, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
To a solution of methyl 4-cyanobenzeneacetate (2.646 g, 15.1 mmol) and iodomethane (2.4 ml) in N,N-dimethylformamide (50 ml) was slowly added 60% oily sodium hydride (1.55 g, 38.8 mmol) under ice-cooling. The reaction mixture was stirred for 2 hours at room temperature. The reaction solution was slowly added to ice water, and extracted with ethyl acetate. The extracts were washed with a saturated aqueous solution of sodium chloride, dried, and concentrated under reduced pressure. The residue was subjected to a silica gel column chromatography (ethyl acetate/hexane 3:1) to give the title compound (2.996 g, yield 98%). 1H NMR (CDCl3) delta 1.59 (6H, s), 3.67 (3H, s), 7.42-7.47 (2H, m), 7.61-7.65 (2H, m).
The synthetic route of 52798-01-3 has been constantly updated, and we look forward to future research findings.
