YieldReaction ConditionsOperation in experiment
EXAMPLE 112a Preparation of intermediate 5-bromo-2-iodo-benzaldehyde To a solution of 5-bromo-2-iodo-benzomitrile (1.54 g, 5 mmol) in DCM (15 mL) was added a solution of DIBALH (6 mL, 6 mmol) dropwise at 0 C. After the addition, the reaction mixture was warmed to r.t. and stirred for 2 h. Then the mixture was poured into 20 g of ice and 20 mL of 1N HCl, filtered and extracted by DCM (40 mL), washed with aqueous sodium bicarbonate, dried over MgSO4 and concentrated to give crude product (Yield: 1.2 g).
Step 1: 5-Bromo-2-iodo-benzaldehyde To <strong>[121554-10-7]5-bromo-2-iodobenzonitrile</strong> (7.4 g, 24.2 mmol) in THF (40 mL) at -78 C. was added diisobutylaluminium hydride (1M in hexanes; 24.2 mL, 24.2 mmol) over 5 minutes, and the reaction was allowed to warm to room temperature and monitored by analytical tlc. After stirring overnight at room temperature, starting material was still present, so the mixture was cooled to 0 C. and additional diisobutylaluminium hydride (1M in hexanes; 10.0 mL, 10.0 mmol) was added. After stirring for 2 hours at room temperature, no starting material was seen by analytical tlc, so the mixture was carefully quenched with freshly saturated aqueous Na2SO4 and diluted with EtOAc. The mixture was stirred vigorously for 1 hour and then filtered through Celite. The filtrate was concentrated, and the resulting oil solidified on standing. The solid was stirred vigorously in CH2Cl2 and 1N aqueous HCl, and the aqueous layer was separated and extracted with CH2Cl2. The combined organic layers were dried over MgSO4, filtered, and concentrated to give the title compound.
T o a s o l u t i o n o f <strong>[121554-10-7]5-bromo-2-iodobenzonitrile</strong> (5.0Og, 16 00mmoles) in anhydrous tetrahydrofuran (80ml) at -8O0C is added diisobutyl aluminium hydride (16.0ml, 16.0mmoles, 1 M solution in toluene) dropwise over 10 minutes. The reaction mixture is stirred at -8O0C for a 1 hour, then allowed to warm to ambient temperature and stir overnight. Additional diisobutyl aluminium hydride (16.0ml, 16.0mmoles, 1 M solution in toluene) is next added dropwise at room temperature, and the reaction mixture further stirred for 1hour. After careful quenching with 2M hydrochloric acid (cooling in ice bath), the crude product is extracted with ethyl acetate (x 2), then all organics are combined and dried over magnesium sulfate and filtered. The filtrate is evaporated under reduced pressure then purified by flash column chromatography (isohexane to 10% ethyl acetate in isohexane eluant) to afford 5-bromo-2- iodobenzaldehyde (0.85g).
