실험 절차

To a solution of 1-(2-azidoethyl)-1H-benzimidazole-5-carboxylic acid (0.82 g, 0.00357 mol) in dry DMF (8.0 mL) was added with stirring HOBt (0.578 g, 0.00428 mol), DIPEA (1.9 mL, 0.0107 mol), 8-azabicyclo[3.2.1]octan-3-ol (0.5 g, 0.00393 mol) and the mixture was cooled to 0° C. To the resulting mixture was added EDCl (0.82 g, 0.00428 mol) and stirred for 15 h at ambient temperature. The reaction mixture was then diluted with ice water (100 mL), extracted with EtOAc (3×50 mL) and the combined organic phases were washed with water (3×50 mL) and saturated brine solution (50 mL). The organic phase was dried (Na2SO4) and the solvent evaporated affording (1.1 g, 98%) of [1-(2-azidoethyl)-1H-benzimidazol-5-yl]-(3-hydroxy-8-azabicyclo[3.2.1]oct-8-yl)methanone. MS-ESI m/z 341 (M+1).
