실험 절차
A solution of n-butyllithium (1.6M) in hexanes (0.18 ml) was added to a solution of diisopropylamine (0.212 ml) in THF (2 ml) at 0° C. The mixture was stirred for 5 min and then cooled to −78° C. 3-Methylthiophene-2-carbonitrile (184 mg, CAS Reg. No. 55406-13-8) was added at −78° C. and then stirred for 30 min. A solution of 2-(4-bromo-2-chlorophenyl)ethanone (248 mg, CAS Reg. No. 749932-89-6, prepared in analogy to Example 58, step 2, from 2-chloro-4-bromoacetophenone [CAS Reg. No. 252561-81-2]) in THF (1 ml) was added at −78° C. The mixture was stirred for 20 min, then water (0.2 ml) was added. The mixture was filtered over celite and concentrated to an oil. The residue was purified by flash chromatography (SiO2, 0 to 100% EtOAc/heptane) to give the title compound (100 mg) as a colorless oil. MS (m/e)=370.0 [M+H+].
