Procedure
4-Bromomethylbenzene sulfonyl chloride (3.72 g, 13.8 mmol) was added portionwise to a solution of 4-amino-1,3,5-trimethyl-1H-pyrazole (1.73 g, 13.8 mmol) and pyridine (1.5 ml) in DCM (100 ml) at rt. Concentration in vacuo gave a solid which was collected by vacuum filtration and washed with water (2×25 ml) then Et2O (100 ml) to give the title compound as a white solid (2.71 g, 7.59 mmol, 55%). δH (D-6 DMSO, 300K) 9.13 (1H, s), 7.64-7.55 (4H, m), 4.77 (2H, s), 3.55 (3H, s), 1.80 (3H, s), 1.54 (3H, s). m/z (ES+, 70V) 358.1 (MH+).
