In tetrahydrofuran; at 0 - 20℃; for 2h; A solution of CH3MgBr (1 .0 M in THF, 0.26 ml_, 2.6 mmol) is added dropwise to a solution of 3-isopropyl-N-methoxy-N-methyl-benzamide (0.5 g, 2.4 mmol) in THF (5 ml_) at 0 C. The reaction mixture is stirred at room temperature for 2 hr and quenched with saturated NH CI followed by extraction with EtOAc (2 x). The organic portions are separated, combined, dried with MgSO4, filtered and concentrated in vacuo to give the desired product 1 -(3-isopropylphenyl)ethanone (0.5g) which is used directly without further purification.

This was followed by the addition of n-BuLi (20 mL, 2.00 equiv) dropwise with stirring at -60 C. The mixture was stirred at -60C for 30 mm. To this was added N-methoxy-N-methylacetamide (3.9 g, 37.82 mmol, 1.50 equiv) dropwise with stirring at -30 C. The resulting solution was stirred for 3 h at -30 C in a liquid N2 bath. The reaction was then quenched by the addition of 20 mL of water. The resulting solution was diluted with 200 mL of EtOAc, washed with 2x100 mL of brine, dried over anhydrous Na2SO4 and concentrated under vacuum. The residue was applied onto a silica gel column with EtOAc/petroleum ether (1:10). This resulted in 2.7 g (66%) of the title product as colorless oil.
