Procedure:
A solution of 101 mg of 2-(3-amino-2-oxopyridin-1(2H)-yl)-N-(2-ethyl-butyl)acetamide (2a, 0.40 mmol) in 2.5 mL of DMF is provided. To this solution, a solution of 121 mg of (S,E)-2-(tert-butoxycarbonylamino)-7-ethoxy-7-oxohept-5-enoic acid (ZED775, 0.40 mmol), 152 mg of HATU (0.40 mmol) and 136 μL of DIPEA (2 eq) in 2.5 mL of DMF is added. By successive addition of DIPEA the pH value is adjusted to ca. 7. The reaction mixture is stirred at 40° C. for 1.5 hours and subsequently at RT overnight, before the solvent is removed in vacuo. The obtained residue is taken up in 75 mL of ethyl acetate and subsequently washed each three times with 10% citric acid, saturated NaHCO3 solution and brine. The organic phase is dried over Na2SO4, filtered and concentrated in vacuo in dryness. Gel is obtained and it is suitable for further processing without further purification.

Procedure:
Compounds of formula A in which Z=2,3-dihydro-2-oxo-1H-benzimidazol-1-yl and L=(N-methylene)piperidin-4-yl are prepared from β-aminotetralins (VII) or phenethylamines (XI) and [4-(2-keto-1-benzimidazolinyl)piperidin-1-yl]acetic acid (Schemes 6-7). For example, 4-(2-keto-1-benzimidazolinyl)piperidine is reacted with a bromoacetic acid ester, such as ethyl bromoacetate, in the presence of an amine base, such as diisopropylethylamine, in an inert solvent such as acetonitrile, at a temperature ranging from ambient temperature to reflux, to afford ethyl [4-(2-keto-1-benzimidazolinyl)piperidin-1-yl]acetate. This ester is subjected to hydrolysis under basic conditions, for example, by treatment with sodium hydroxide in an alcoholic solution such as aqueous methanol, to yield, upon acidification with an inorganic or organic acid such as hydrochloric or acetic acid for example, [4-(2-keto-1-benzimnidazolinyl)piperidin-1-yl]acetic acid. This carboxylic acid is reacted directly with β-aminotetralins (VII) or phenethylamines (XI), in the presence of an amine base, under peptide coupling conditions described above, to afford benzimidazolinones (XVII) and (XVIII) of formula A in which Y =carbonyl and L=(N-methylene)piperidin-4-yl (Schemes 6-7).

Procedure:
(3S)-3-(Dimethylamino)pyrrolidine (90 μl, 0.71 mmol) and triethylamine (200 μl) were added to a dimethyl sulfoxide (5 ml) solution of 7-fluoro-5-methyl-2-(2-nitrophenyl)-6-phenyl-1,3-benzoxazole-4-carbonitrile (I-210) (204 mg, 0.55 mmol). The system was purged with nitrogen, then sealed up, and heated at 100° C. for 1.5 hours. After cooling, the solvent was evaporated away under reduced pressure, then the resulting residue was dissolved in chloroform, and washed with water and saturated brine. The organic layer was dried over anhydrous sodium sulfate, then the solvent was evaporated away under reduced pressure, and the resulting residue was subjected to silica gel column chromatography. Elution with a mixed solvent of chloroform/methanol (98:2, v/v) gave a main product. This was washed with a mixed solvent of isopropyl ether and ethanol, and the solid was collected by filtration to obtain the entitled compound (137 mg, 54%) as a yellow solid.
