Reaction Steps
1H-benzo[d]imidazole-2-carboxylic acid (1.788 g, 11.03 mmol) was dissolved in 50 ml DMF and HATU (4.19 g, 11.03 mmol) was added. This mixture (A) was stirred for 30 min. 3-hydroxyazetidine hydrochloride (1.2083 g, 11.03 mmol) was added to 50 ml DMF, diisopropylethyl amine (5.76 mL, 33.1 mmol) was added and the mixture (B) was stirred for 5 min. Mixture (B) was added to mixture (A) and the resulting reaction mixture was stirred for 6 hours. The reaction was hydrolyzed with 30 ml water and 30 ml 1M HCl and the resulting mixture was extracted with EtOAc (3×200 ml). The combined organic layers were dried with magnesium sulfate and evaporated. Silica gel chromatography (0-10% MeOH in DCM) provided (1H-benzo[d]imidazol-2-yl)(3-hydroxyazetidin-1-yl)methanone (0.570 g, 2.62 mmol, 23.79% yield) as a yellow oil.
