実験手順

The intermediate, N-benzimidazolyl-1,2-propanediol (0.66 g 3.4 mmol) from above was dissolved in water (25 mL) and treated with sodium periodate (0.88 g, 4.1 mmol) with stirring for 1.5 hours. The solution was then extracted with dichloromethane, dried (MgSO4), filtered and concentrated to yield 2-(benzimidazol-1-yl)-ethanal (0.22 g, 1.4 mmol) which was used immediately without further purification in the next reaction.
