A suspension of dimethylamine hydrochloride (2.45 g, 30 mmol) in dichloromethane (150 ml) was cooled in an ice/methanol bath and then treated with triethylamine (6.0 g, 59 mmol) followed by 4-iodobenzoyl chloride (8.0 g, 30 mmol) portionwise with stirring under an atmosphere of argon. The reaction mixture was allowed to stir at room temperature for 30 minutes before the solution was washed with water (2×100 ml). The organic layer was separated, dried over sodium sulphate, and evaporated under reduced pressure to give the title compound as a light beige coloured solid (7.73 g, 94%).
