Reaction Steps

To a stirred solution of methyl 3-[3,5-dimethyl-1-(4-{2-[(methylsulfonyl)oxy]ethyl}phenyl)-1H-pyrazol-4-yl]benzoate (step 2, 2.0 mmol) and KI (330 mg, 2.0 mmol) in N,N-dimethylformamide (10 mL) was added sodium azide (260 mg, 4.0 mmol), and then the resulting mixture was stirred for 1.5 h at 100° C. The reaction mixture was poured into water (100 mL), and extracted with ethyl acetate/toluene (4:1). The organic layer was washed with water (50 mL) and brine (50 mL), then dried (Na2SO4). After removal of the solvent, the crude product was purified by TLC with hexane/ethyl acetate (1:1) to give the title compound as yellow oil (quant.): 1H-NMR (CDCl3) δ 8.01 (2H, s), 7.53-7.34 (6H, m), 3.95 (3H, s), 3.55 (2H, t, J=7.1 Hz), 2.96 (2H, t, J=7.1 Hz), 2.33 (3H, s), 2.30 (3H, s).
