Reaction Steps

step 3—To a solution of 100 (0.24 g, 0.85 mmol) and TEA (0.18mL, 1.3 mmol) in DCM (10 mL) at 0° C. was added 4-nitrobenzoyl chloride (0.19 g, 1.0 mmol). The resulting mixture was stirred at 0° C. for 3 h, and then warmed to RT. The mixture was then diluted with additional DCM, washed sequentially with water and brine, dried (Na2SO4), filtered and concentrated. The crude residue so obtained was purified by SiO2 chromatography eluting with EtOAc/hexane to afford 0.36 g (97%) of N-[3-tert-butyl-2-methoxy-5-(2-methoxypyridin-3-yl)phenyl]-4-nitrobenzamide (102) as a light yellow solid.
