Procedure

A solution of 4-(bromomethyl)benzenesulfonyl chloride (5.6 mmol) in 5 mL of CH2Cl2 at 25° C. is treated with Et3N (8.4 mmol) followed by bis-(4-methoxy-benzyl)-amine (5.8 mmol). The reaction is stirred for 12 hours, diluted with H2O, extracted with CH2Cl2, dried (MgSO4), filtered and concentrated. The resultant crude material is purified by silica flash chromatography (20% EtOAc/hexanes) to yield 4-bromomethyl-N,N-bis-(4-methoxy-benzyl)-benzenesulfonamide: 1H NMR (400 MHz, CDCl3): δ 7.72 (apparent t, J=8.4 Hz, 2H), 7.44 (dd, J1=1.6 Hz, J2=8.4 Hz, 2H), 6.91-6.86 (m, 4H), 6.69 (d, J=8.8 Hz, 4H), 4.5 (s, 2H), 4.19 (s, 4H), 3.71 (s, 3H); LC/MS: (ES+) 490.1 (M+1)+.
