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%).
