Reaction Conditions

Reaction Steps

To a stirred solution of (4-bromophenyl)phenyl methanone (0.750 g, 2.87 mmol) in anhydrous THF (25.00 mL) was added solution of methylmagnesium bromide in THF (3.00 M, 1.91 mL) via a syringe at −78° C. The resulting mixture was stirred for 2 hours at −78° C. The reaction was quenched with 10 mL of a saturated aqueous NH4Cl solution at −78° C. and allowed to warm to rt. The product was extracted with EtOAc (2×) and brine (2×). The aqueous layer was back-extracted with DCM several times. The organic layers were combined, dried, filtered and concentrated in vacuo to give the product which was used for next step without any further purification. 1H NMR (400 MHz, CDCl3): δ 1.90 (3H, s) 7.19-7.33 (5H, m) 7.33-7.43 (4H, m).
