5264-35-7, 5-Methoxy-3,4-dihydro-2H-pyrrole is a pyrrolines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated,5264-35-7
a) The corresponding Grignard compound is prepared from 22.6 g of 4-bromobiphenyl with 2.36 g of magnesium in 75 ml of THF. A solution of 8.0 g of 5-methoxy-2H-3,4-dihydropyrrole in 25 ml of THF is added dropwise to this solution. The mixture is boiled at reflux for 5 hrs., then poured into a saturated solution of ammonium chloride, extracted with ethyl acetate, dried and concentrated. The residue is recrystallized from isopropanol, with 1.93 g of 5-biphenylyl-2H-3,4-dihydropyrrole being isolated, m.p. 230¡ã C.
As the paragraph descriping shows that 5264-35-7 is playing an increasingly important role.
