YieldReaction ConditionsOperation in experiment
In methanol; for 16h;Heating / reflux; [0247] 3-Iodobenzylguanidine (3.9). To a solution containing 168 mg (721 mumol) of 3.8 in 1 mL of methanol was added 90.1 mg (726 mumol) of 3.7. The reaction solution was refluxed for 16 h and then concentrated under reduced pressure to give 3.9 as a viscous yellow gum: yield 258 mg. HPLC analysis was preformed using a nucleosil C18 reversed-phase column. A retention time of 24.54 min was generated when the column was eluted with 80% H2O (0.01 M NaH2PO4): 20% CH3CN at a flow rate of 2.0 mL/min and lambda=231 nm. 1H NMR (MeOH, 200 MHz): delta 4.22 (s, 2H), 6.99 (t, 1H), 7.22 (d, 1H), 7.49 (d, 1H), 7.56 (s, 1H). 13C NMR (MeOH, 50.3 MHz): delta 48.95, 99.31, 131.64, 135.72, 141.05, 141.93, 144.30, 162.65. IR (thin film): 3407, 3192, 1653, 1115 cm-1. MS (ESMS, methanol), m/z 276.1 [M+H]+.

YieldReaction ConditionsOperation in experiment
89% With triethylamine; In dichloromethane; at 20℃; for 4.5h; In a 100 rnL round-bottom flask with magnetic stirrer and balloon (for pressure equalization and exclusion of moisture), a solution of di-tert-buty dicarbonate (0.72 g, 3.3 mmol, 1.2 equiv.) in CH2Cl2 (5 mL) was added all at once at room temperature to a solution of 3-iodobenzylamine (641 mg, 2.75 mmol) and triethylamine (0.57 mL, 4.1 mmol, 1.5 equiv.) in CH2Cl2 (10 mL). The mixture was stirred at room temperature for 4.5 h. TLC after 3.5 h (SiO2, EtOAc/hexane/Et3N 22:78:5) indicated complete conversion of the amine (Rf approx. 0.05), whereas a strongly UV-active impurity (R{ approx. 0.65) remained unchanged, and the product was detected at R{ approx. 0.55. With EtOAc/hexane 1:9 as eluent, product and impurity exhibit R{ values of approx. 0.2 and 0.4, respectively. The reaction mixture was evaporated, and the residue was chromato graphed on SiO2 (26 x 3.8 cm, EtOAc/hexane 6:94 until the nonpolar impurity was completely eluted, then 1:4). Evaporation and drying (40 C/oil pump) furnished 820 mg (89%) of a colorless solid. Mp 53.5-54.5 0C.

88% In dichloromethane; at 20℃; for 12h; To a stirred solution containing 1 mL (7.5 MMOL) of 3-iodobenzylamine and 15 mL of DICHLOROMETHANE was added 1.7 g (7.87 MMOL) of di-tert-butyl dicarbonate. The reaction mixture was allowed to stir at room temperature for 12 h, then diluted with ether and washed successively with water, 10% aqueous NAOH, 10% aqueous HCI, and brine, and dried over MGS04. The solvents were removed under reduced pressure to give the title compound as a white solid (2.20g, 88%). 1H NMR (300 MHz, CDCI3) 95 1. 45 (s, 9H), 4.26 (d, 2H, J = 6.0 Hz), 4.83 (brs, 1H), 7.05 (dd, 1H, J = 7.5 and 7.5 Hz), 7.24 (d, 1H, J = 7.5 Hz), 7.58 (d, 1 H, J = 7.5 Hz), and 7.62 (s, 1 H).

The mixture was stirred at room temperature for 4.5 h. TLC after 3.5 h (SiO2, EtOAc/hexane/Et3N 22:78:5) indicated complete conversion of the amine (Rf approx. 0.05), whereas a strongly UV-active impurity (Rf approx. 0.65) remained unchanged, and the product was detected at Rf approx. 0.55. With EtOAc/hexane 1:9 as eluent, product and impurity exhibit Rf values of approx. 0.2 and 0.4, respectively. The reaction mixture was evaporated, and the residue was chromatographed on SiO2 (26×3.8 cm, EtOAc/ hexane 6:94 until the nonpolar impurity was completely eluted, then 1:4). Evaporation and drying (40 C./oil pump) furnished 820 mg (89%) of a colorless solid. Mp 53.5-54.5 C.
