Ammonium Chloride → 1-(2'-(Benzyloxy)-3'-phenybiphenyl-3-yl)-1-(2-methoxyphenyl)ethanol

Participants

Reaction Steps

A solution of 32 (1.5 g, 3.96 mmol) in anhydrous tetrahydrofuran (16 mL) was stirred under nitrogen at room temperature and 1M ortho-methoxyphenyl magnesium bromide in tetrahydrofuran (6 mL, 1.5 equiv.) was slowly added. Stirring was continued at room temperature for 30 min and at 60° C. for 3 hr. After cooling, the reaction mixture was poured on saturated ammonium chloride (100 mL) and extracted with ethyl acetate (150 mL). The organic extract was washed with water (2×100 mL), dried over sodium sulfate and filtered. The solvent was removed in a rotary evaporator and the crude 33 thus obtained was used in the next step without further purification.
