A balanced equation for a chemical reaction indicates what is reacting and what is produced, but it reveals nothing about how the reaction actually takes place. The reaction mechanism is the process, or pathway, by which a reaction occurs.69778-83-2, name is 4-Methoxy-1H-pyrrol-2(5H)-one. An updated downstream synthesis route of 69778-83-2 as follows., 69778-83-2
EXAMPLE 2 (Z)-4-methoxy-5-(cyclohexylmethylene)-3-pyrrolin-2-one (IV, R2 =H, R3 =Me, R4 =cyclohexyl) 23.9 g of 4-methoxy-3-pyrrolin-2-one (94.6 percent) in 1360 ml of 4 n sodium hydroxide solution and 27.5 g of cyclohexanecarbaldehyde (90 to 95 percent) in 330 ml of methanol were reacted as described in Example 1. Data for the product was: Yield: 39.8 g (96.1 percent) Melting point: 134¡ã to 136¡ã C., colorless crystals 1 H-NMR: delta=9.07 (br.s, 1H), 5.32 (d, 1H), 5.14 (d, 1H), 3.83 (s, 3H), 2.40 (m, 1H), 1.09-1.81 (m, 10H)
