20232-39-7, In a 100-ml two-necked round bottom flask equipped with a mechanical stirrer, an addition funnel and an argon in/outlet, 5.0 g of 1 was suspended in 19 ml of heptane at room temperature. 19 ml of MeOH was added over 15 minutes and stirring was continued for 1 h. A 200-ml four-necked round bottom flask equipped with a mechanical stirrer, an addition funnel and an argon in/outlet was charged with 7.4 g of 2, 268.0 mg of NaOAc and 1.9 ml of H2O in 56 ml of MeOH. To this mixture was added over 1.5 h the previously prepared emulsion and, after 1 h, 333 mul of conc. aqueous HCl was added. 55 ml of heptane was added over 30 minutes. The yellow suspension was stirred for 2 h at room temperature, filtered and washed portionwise with 12 ml of MeOH and 24 ml of heptane (cooled to 0¡ã C.). Evaporation of the solvent and drying under high vacuum gave 9.37 g (84percent) of 3b as an off-white solid.
20232-39-7 6,7-Dimethoxy-3,4-dihydroisoquinoline hydrochloride 2724664, aisoquinoline compound, is more and more widely used in various fields.
