Related Products of 14254-57-0 ,Some common heterocyclic compound, 14254-57-0, molecular formula is C6H4ClNO, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.
A solution of (1R,2S,3R,5R)-3-amino-5-(hydroxymethyl)cyclopentane-1,2-diyl dibenzoate hydrochloride (150. mg, 0.380 mmol) in DCM (10.0 mL) at 0 C. was treated with EtN (0.170 mL, 1.22 mmol) and stirred for 20 min. Isonicotinoyl chloride (88.0 mg, 0.490 mmol) was then added and the mixture was stirred for 2 h. The reaction was treated with saturated aqueous solution of ammonium chloride (50 mL) and extracted with DCM (2¡Á50 mL). The combined organic layers were dried over sodium sulfate, filtered and concentrated in vacuo. The resulting residue was purified via silica gel chromatography eluting with a gradient of 0 to 10% MeOH in DCM to afford the title compound (100. mg, 60%). LC/MS: Rt=1.49 min, ES+ 461 (FA standard).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,14254-57-0, its application will become more common.
