Example R: Preparation of 4-bromo-2-ethylbenzaldehydeTo a solution of <strong>[175278-30-5]4-bromo-2-ethyl-1-iodobenzene</strong> (75 g, 0.24 mol) in tetrahydrofuran (375 ml) at - 75 0C is added n-butyl lithium (1.6 M in hexanes, 196 ml, 0.31 mol) dropwise, maintaining the temperature of the reaction mixture below -70 °C. When the addition is complete the mixture is stirred at -75 0C for an additional 30 minutes and then lambda/,lambda/-dimethylformamide (70.7 g, 0.97 mol) is added dropwise. After the addition is complete the reaction is stirred at -75 °C for 2 hours, then allowed to warm to room temperature for 2 hours. The mixture is cooled in an ice bath and acidified with 0.5 N aqueous hydrochloric acid. The mixture is extracted with ethyl acetate (3 x 500 ml) and the organic fractions are combined, washed with brine, and dried over anhydrous sodium sulphate. The mixture is filtered and the filtrate is evaporated under reduced pressure. The residue is purified by column chromatography on silica gel to give 4-bromo-2- ethylbenzaldehyde (48 g) as an oil. |

62% | Method 1 : To a solution of <strong>[175278-30-5]4-bromo-2-ethyliodobenzene</strong> (1 .61 mmol, 0.5 g) dissolved in anhydride THF (6 mL) at -785C was added 2.5 M n-butyllithium solution in hexane (1 .9 mmol, 0.77 mL) dropwise. The mixture was stirred 30 min at -78 5C before /V-formylmorpholine (3.69 mmol, 0.37 mL) was added and the reaction stirred at this temperature for 1 h. The reaction was quenched with aqueous 1 N HCI and extracted with EtAcO. The combined organic extracts were washed with brine, dried over anhydrous sodium sulfate, filtered and concentrated. Purification of the crude material by flash chromatography on silica gel using an elution of 3percent ethylacetate in hexanes afforded the title compound (21 1 mg, 62percent). 1 H (400 MHz, CDCI3) delta 10.24 (1 H, s), 7.69 (1 H, d, J = 8.4 Hz), 7.51 (1 H, dd, J = 8.4 & 2 Hz), 7.48 (1 H, d, J = 2 Hz), 3.05 (2H, q, J = 7.6 Hz), 1 .28 (3H, t, J = 7.6 Hz).
