실험 절차
To 5-phenylthiazol-2-amine (0.52 g, 2.9 mmol) in acetonitrile (6 mL) was added 1,1′-thiocarbonyldiimidazole (0.68 g, 3.8 mmol). The reaction mixture was stirred at 65° C. for 2 hours. The precipitate was filtered and washed with acetonitrile (2×20 mL) to yield intermediate N-(5-phenylthiazol-2-yl)-1H-imidazole-1-carbothioamide. The intermediate was taken up in N,N-dimethylformamide (30 mL) and treated with (3-(aminomethyl)-3-hydroxy-1-ammoniobicyclo[2.2.2]octan-1-yl)trihydroborate (0.5 g, 2.9 mmol). The reaction mixture was stirred for 5 hours at 65° C. The reaction was concentrated in vacuo and purified via silica gel chromatography (30-100% ethyl acetate/hexane). The product fractions were combined and concentrated in vacuo to yield (3-hydroxy-3-((3-(5-phenylthiazol-2-yl)thioureido)methyl)-1-ammoniobicyclo[2.2.2]octan-1-yl)trihydroborate (0.85 g, 2.19 mmol, 74.4% yield) as a white powder. LC/MS confirmed product with loss of BH3 in the LC/MS conditions: retention time 3.26 (M+1-BH3=375.33).
