58-74-2, 1-(3,4-Dimethoxybenzyl)-6,7-dimethoxyisoquinoline is a isoquinoline compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
EXAMPLE II Preparation of 6,7-Dimethoxy-1-[(alpha-piperidinomethyl)-veratryl]isoquinoline dihydrochloride (P3138) A mixture of 10.2 g (0.03 mole) of papaverine, 1.2 g (0.04 mole) of paraformaldehyde, 4.9 g (0.04 mole) of piperidine hydrochloride and 150 ml of ethyl alcohol were heated at reflux for 7 hours. The solvent was removed from the reaction mixture by evaporation and the residue dissolved in 100 ml of water. The solution was made basic (pH of 10) by addition of 50 percent aqueous sodium hydroxide solution and the resulting mixture extracted with two 100 ml portions of benzene. The benzene extracts were combined and washed with two 100 ml portions of water and finally with 100 ml of aqueous saturated sodium chloride solution. The benzene layer was evaporated and the residue dissolved in 250 ml of acetone. The dihydrochloride salt of the product was precipitated by the addition of hydrogen chloride.
As the paragraph descriping shows that 58-74-2 is playing an increasingly important role.
