Application of 40400-15-5,Some common heterocyclic compound, 40400-15-5, name is 2-(2-Iodophenyl)acetonitrile, molecular formula is C8H6IN, 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 suspension of (2-iodo-phenyl)-acetonitrile (Aldrich, 2.4 g, 10 mmol) and 2,3-difluorophenylboronic acid (Aldrich, 2.4 g, 15 mmol) in anhydrous methanol (10 mL) and toluene (20 mL) was added Cs2CO3 (9.8 g, 30 mmol). The mixture was degassed with nitrogen, followed by the addition of tetrakis(triphenylphosphine)palladium (1.2 g, 1 mmol). [0504] The reaction mixture was heated at 80 C. and stirred for 18 h. The mixture was cooled to room temperature and filtered through a short pad of silica gel. The silica gel was washed with ethyl acetate. The filtrate was concentrated. The residue was purified by chromatography (10-30% ethyl acetate in hexanes) to give the product ( 101) as a colorless oil (1.4 g, 62%)
The synthetic route of 40400-15-5 has been constantly updated, and we look forward to future research findings.
