Reaction Steps

Dissolve 2-(4-chloro-phenyl)-4-methyl-thiophene (0.53 g, 1.85 mmol) in THF (25 mL) and cool to −78° C. Add t-BuLi (1.7 M, 2.3 mL, 3.88 mmol) dropwise. Stir the solution at −78° C. for 20 min. Cannulate the solution into a flask containing powdered dry ice (10 g). Stir the reaction and allow to warm to RT. Quench the reaction with saturated NH4Cl (10 mL), dilute with water (40 mL), and extract with EtOAc (2×50 mL). Dry the combined organic layers over Na2SO4, filter, and concentrate. Purify the crude material by washing with hexane (2×20 mL) to give 0.35 g (74%) of the title compound. LC-MS/ES m/z (35Cl) 251.0 [M−H]−.
