Triethylamine → HCID 69203390, compound

Participants

Reaction Steps

To a solution of Example 5 (300 mg, 1.70 mmol) in N,N-dimethylformamide (3 mL) was added dimethyl amine hydrochloride (139 mg, 1.70 mmol), 1-hydroxybenzotriazole hydrate (253 mg, 1.87 mmol), triethylamine (0.48 mL, 3.4 mmol) and 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (358 mg, 1.87 mmol). The reaction mixture was stirred at room temperature overnight, quenched by addition of saturated aqueous sodium bicarbonate, and extracted with ethyl acetate. The combined organic extracts were dried (Na2SO4), filtered, and concentrated under vacuum. The residue was purified by flash column chromatography on silica gel using dichloromethane/methanol (20:1) as the mobile phase to provide the desired product. MS (APCI): m/z 204 (M+H)+.
