실험 절차

A solution of [3-(2-methoxy-2-oxoethyl)-4,6-dimethyl-2-oxo-2,3-dihydro-1H-benzimidazol-1-yl]acetic acid (Intermediate 9) (305 mg, 1.04 mmol), N,N-dimethylamine hydrochloride (128 mg, 1.60 mmol), EDC (300 mg, 1.60 mmol), HOBT (240 mg, 1.60 mmol), and N, N-diisopropylethylamine (0.909 mL, 5.20 mmol) were stirred for 16 h at ambient temperature in DMF (3 mL). The mixture was partitioned between CH2Cl2 (10 mL) and saturated NaHCO3 (10 mL) and the organic layer was dried over Na2SO4, filtered, and concentrated to give the compound. MS: m/z=320 (M+1).
