Reaction Steps

1-(4-{3-[1-(1H-benzoimidazole-2-carbonyl)-azetidin-3-yl]-pyrazin-2-yl}-phenyl)-ethanone (100 mg, 0.25 mmol, Scheme 2, Example 2.21) was dissolved in 10 ml of methanol. This solution was cooled down to 0° C. using an ice bath and sodium tetraborohydride (19 mg, 0.50 mmol) was added by portions. The reaction mixture was stirred for 4 h at ambient temperature, then saturated aqueous solution of ammonium chloride (5 mL) was added. The methanol was evaporated off under reduced pressure then the reaction mixture was taken up in ethyl acetate. The organic phase was separated from the aqueous phase. This extraction was repeated one more time and then the organic phases were combined and dried over magnesium sulphate, followed by concentrating under reduced pressure. The residue was purified by column chromatography to give the title compound (75 mg, 0.19 mmol, 75% yield).
