Reaction Steps

The above 1-(3-methoxybenzyl)-4-hydroxymethyl-6,7-dimethoxyisoquinoline (339 mg, 1.0 mmol) was dissolved in 5 ml of methylene chloride. Then at −30° C., triethylamine (160 ul, 1.10 eq) and methanesulfonyl chloride (85 ul, 1.10 eq) was added. The mixture was stirred at −30° C. for 30 minutes and then at room temperature overnight. The mixture was extracted with methylene chloride and water. After evaporation of solvents, a solid was obtained to give 1-(3-methoxybenzyl)-4-chloromethyl-6,7-dimethoxyisoquinoline (361 mg, 100%). ES-MS calculated for C20H20O3NCl (m/e) 357.39, observed 358.5 (M+1).
