Procedure

A solution of 3-(chloromethyl)benzoyl chloride (426 μL, 3 mmol) and Et3N (626 μL, 4.5 mmol) in THF (5 mL) was treated with dimethylamine (1.5 mL, 2-M in THF, 3 mmol), stirred at room temperature for 1 h, poured into water, extracted with EtOAc, dried (MgSO4) and concentrated in vacuo to give the title compound (580 mg, 98%) as a colourless oil; NMR δH (400 MHz, CDCl3) 7.46-7.34 (4H, m), 4.59 (2H, s), 3.11 (3H, s) and 2.98 (3H, s); Anal. Calcd for C12H12N6O2.0.2H2O: C, 49.38; H, 4.28; N, 28.79. Found: C, 49.25; H, 4.09; N, 28.47.
