実験手順

A solution of 2-aminoacetaldehyde dimethylacetal (12.3 mL, 112 mmol) in a mixture of acetone (50 mL) and aqueous potassium bicarbonate (12 g, 122 mmol in 110 mL of water) was stirred and cooled to −5° C., as a solution of 4-iodobenzoyl chloride (25 g, 94 mmol) was added dropwise. The cooling bath was removed and the reaction stirred for 3 hours. The reaction was concentrated and diluted with water. The resulting solid was isolated by filtration and dried to give 30.5 g of N-(2,2-dimethoxyethyl)-4-iodobenzamide, 1H NMR (400 MHz, CDCl3) δ 7.78 (d, 2H), 7.46 (d, 2H), 6.34 (s, 1H), 4.44 (t, 1H), 3.58 (t, 2H), 3.42 (s, 6H) ppm.
