Procedure
-
A solution of 4-bromophenethylamine (200 mg, 1.00 mmol), DIEA (509 µL, 3.00 mmol) and praxadine (147 mg, 1.00 mmol) in DMF (1.7 mL) was stirred at ambient temperature for 2 days. The reaction mixture was concentrated and the residue was washed with dichloromethane/2-propanol (4:1 (vol/vol)). The guanidinylated compound 1 was obtained as a pale yellow solid (164 mg, 67% yield.) after filtration.

- Synthesis and pharmacological characterization of a new benzoxazole derivative as a potent 5-HT3 receptor agonist
1-Amidinopyrazole hydrochloride (1 g, 6.8 mmol) is added to a solution of 2-(benzoxazol-2-yl)ethylamine (1.1 g, 6.7 mmol) and diisopropylethylamine (4.75 mL, 27 mmol) in DMF (10 mL). The reaction mixture is stirred at room temperature under N2 for 24 h. Subsequently, diethylether (75 mL) is added, the upper layer is decanted and the remaining oil solidified by treatment with CH2Cl2. The solid is collected, washed with diethylether, CH2Cl2, and CHCl3 : i-PrOH (4 : 1) and dried to yield the product (0.86 g, Y. 52.6%).
