150-78-7, name is 1,4-Dimethoxybenzene, belongs to ethers-buliding-blocks compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. HPLC of Formula: C8H10O2
Example 1 : Preparation of 2,5-dimethoxybromobenzene (1); [00101] In a one liter round-bottom flask, a solution of bromine (16.0 g, 100 mmol) in acetic acid (50 ml) was added dropwise to a solution of 1 ,4- dimethoxybenzene (13.8 g, 100 mmol) in chloroform and methanol (400 ml) at 00C. After stirring for 3 hours, 500 ml of saturated Na2CO3 solution was added. The organic layer was washed with water, brine and dried over sodium sulfate. After the solvent was removed on a rotary evaporator, the residue was distilled under reduced pressure to yield 15.8 g of 2,5- dimethoxybromobenzene (yield 73%) 1HNMR (CDCI3) 57.148 (s, 1 H), 6.859 EPO
The synthetic route of 150-78-7 has been constantly updated, and we look forward to future research findings.
