Yield	Reaction Conditions	Operation in experiment
	In acetonitrile for 5h;	120 5ML of acetonitrile solution was added to 345mg of 3,4-dihydro-[741] 6,7-dimethoxy-l-undecylisoquinoline-6-amine and 242mg of -t - butyl-S-chloromethy^phenylcabamate. Then, the resulting mixture was heated and stirred for 5 hours. The solvent was concentrated under reduced pressure, and the reaction mixture was separated through silica-gel column chromatography eluting with dichloromethane and methanol(10:l), to give 0.4Og of solid compound, 2-{A-t - butylalcohol carbonyl- [742] aminophenyl)methyl-3,4-dihydro-6,7-dimethoxy-l-undecylisoquinolinium chloride(m.p.l42°C).

Yield	Reaction Conditions	Operation in experiment
50%	With pyridine; thionyl chloride; In dichloromethane; for 0.5h;	B. To a stirred solution of /<?/-/-butyl 4-(hydroxymethyl)phenylcarbamate (0.50 g. 2.24 mmol) in dichloromethane was added pyridine (3 drops), followed by the dropwise addition of thionyl chloride (0.35 mL. 4.98 mmol). The resulting reaction mixture was stirred for 30 minutes, and then quenched with water (25 mL). The aqueous layer was extracted with dichloromethane (50 mL). and the organic layer was dried over sodium sulfate, filtered and concentrated in vacuo to afford /<?/7-butyl 4-(chloromethyl)- phenylcarbamate as an orange solid in 50% yield (0.27 g. 50%): 1H NMR (300 MHz. CDCl3) delta 7.38-7.28 (m. 4H). 6.51 (br s. I H). 4.55 (s. 2H). 1.52 (s. 9H).
	With methanesulfonyl chloride; triethylamine; In tetrahydrofuran; at 0 - 25℃; for 16h;	To a mixture of <strong>[144072-29-7]tert-butyl (4-(hydroxymethyl)phenyl)carbamate</strong> (2.00 g, 8.96 mmol), TEA (1.81 g, 17.9 mmol) in THF (30 mL) was added MsCl (1.33 g, 11.6 mmol) dropwise at O C and stirred for 0.5 hour. Then warmed to 25 C and stirred for another 15.5 hours to give a yellow suspension. TLC (PE/EtOAc = 5: 1) showed the reaction was completed. The mixture was quenched with ice water (80 mL) slowly, then extracted with EtOAc (60 mL x2), the combined extracts were washed with brine (80 mL x2), dried over Na2S04, filtered and concentrated under reduced pressure to give tert-butyl (4- (chloromethyl)phenyl)carbamate (2.16 g, crude) as a pale yellow gum
