Procedure

Under ice-cooling, tert-butyl 2-(5-(bromomethyl)-2-(methoxymethoxy)benzamido)-4-phenylbenzoate (0.12 g) was added to an acetone (1.8 mL) solution of N,N,N′-trimethylethylenediamine (0.089 mL), followed by stirring at room temperature for 1 hour. The solvent was evaporated under reduced pressure, and a saturated aqueous solution of sodium bicarbonate and chloroform were added to the residue. The organic layer was separated and dried over anhydrous sodium sulfate, and the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography [eluent: 100-90% chloroform/methanol] to obtain 0.070 g of tert-butyl 2-(5-(((2-(dimethylamino)ethyl)(methyl)amino)methyl)-2-(methoxymethoxy)benzamido)-4-phenylbenzoate.
