참여 물질

반응 단계

A solution of 8-bromo-5-fluoro-1,2,3,4-tetrahydro-isoquinoline hydrochloride (200 mg, 0.75 mmol, 1.0 eq.) and the acid (1R,2R)-2-phenyl-cyclopropanecarboxylic acid (122 mg, 0.75 mmol, 1.0 eq.) in DMF (9 mL) was treated with 4-(dimethylamino)pyridine (367 mg, 3.00 mmol, 4.0 eq.) and N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (216 mg, 1.13 mmol, 1.5 eq.) and the resulting solution was stirred at r.t. for 18 hours. The reaction mixture was diluted with AcOEt (70 mL). The diluted solution was washed with 1N aq. HCl (3×30 mL), sat. aq. NaCl soln. (1×30 mL), dried over MgSO4, filtered, and concentrated in vacuo to give the desired compound as a pale yellow oil. The product was used without further purification.
