The synthetic route is as follows., 51554-93-9

General procedure: A 3-neck round-bottomed flask equipped with a thermometer and a condenser was flame-dried and flushed with Ar. The flask was then charged with Mg0 (1.1 eq.), a single I2 crystal and another vacuum/Ar cycle was performed. Et2O (C=0.65M) was added resulting in a bright orange suspension of Mg0 pellets. Phenyl octyl bromide (1.0 eq.) was then added in one portion and the suspension was heated via a heatgun until the internal temperature reached 32C and stabilized for 5-10s, indicating that the Grignard formation had started. The reaction was stirred at rt until disappearance of the starting material by 1H NMR analysis (e.g.?1h). (0031) The Grignard solution (3.0 eq., C=0.65M) was then syringed to another flask containing substrate (1.0. eq.) in dry Et2O (C=0.05M). The solution was stirred at rt until disappearance of the starting material by TLC analysis. Saturated aqueous NH4Cl solution was added and the aqueous layer was extracted x2 with EtOAc. The organic layers were collected, washed x1 brine, dried over Na2SO4, filtered, concentrated in vacuo.
