Reaction Steps

Methyl 6-(3,5-dimethylisoxazol-4-yl)-2-oxo-2,3-dihydro-1H-benzo[d]imidazole-4-carboxylate (100 mg, 0.35 mmol) was dissolved in 5 mL of THF and stirred at room temperature followed by the addition of isopropylmagnesium bromide (0.87 mL, 2.0 mmol). Addition Grignard was added in 1 hour intervals until the starting material was consumed. Once complete, the crude reaction mixture was quenched with DI water and extracted 3× with ethyl acetate. Combined organic layers were washed with brine, dried over sodium sulphate, filtered, concentrated in vacuo, and purified via HPLC.
