Reaction Steps

To the solution of 166 (170 mg, 0.69 mmol) in DCM (5 mL) was added EDC.HCl (190 mg, 1 mmol), HOBt (160 mg, 1 mmol), TEA (0.3 mL) and N-methoxymethanamine hydrochloride (100 mg, 1 mmol). The mixture was stirred at RT overnight. The mixture was poured into water, extracted with EtOAc, washed sequentially with H2O and brine, dried (Na2SO4), filtered and concentrated in vacuo. The crude product was purified by SiO2 chromatography affording 140 mg (85%) of 1-(tetrahydro-pyran-2-yl)-1H-benzoimidazole-5-carboxylic acid methoxy-methyl-amide (168) as a light yellow oil.
