Reaction Conditions

Reaction Steps

A solution of 1-(3-sec-butoxy-benzyl)-4-chloromethyl-6,7-dimethoxy-isoquinoline (1.0 g, 2.5 mmol) in dimethylsulfoxide (2 mL) was added to a solution of sodium azide (813 mg, 12.5 mmol) in dimethylsulfoxide (10 mL) prewarmed to 65° C. The solution was stirred at 65° C. for 1½ hrs. The reaction mixture was cooled and dissolved in ethyl acetate (100 mL). This ethyl acetate solution was washed with saturated aqueous sodium bicarbonate solution (2×20 mL), saturated aqueous sodium chloride solution (20 mL), dried over magnesium sulfate, filtered and concentrated in vacuo to afford 4-azidomethyl-1-(3-sec-butoxy-benzyl)-6,7-dimethoxy-isoquinoline (550 mg, 54%) as a light yellow solid which was used without further purification: APCI-MS m/e calcd for C23H26N4O3 (M+H+) 407.5, found 406.9; 1H NMR (300 MHz) compatible.
