2,4,6-Trichloro-5-pyrimidinecarboxaldehyde → 2,4-Dichloro-6-(2-(isopropylsulfonyl)phenylamino)pyrimidine-5-carbaldehyde

참여 물질

반응 단계

To a stirred solution of 2,4,6-trichloropyrimidine-5-carbaldehyde (5.0 g, 23.8 mmol) in DCM (50 mL) was added 2-(isopropylsulfonyl)aniline (9.5 g, 47.6 mmol) at 0° C. under nitrogen atmosphere. The reaction mixture was warmed to room temperature gradually and stirred overnight. The solid was filtered off, and the filtrate was concentrated in vacuo and purified by silica gel chromatography (DCM/EtOAC/Hexanes: 15/15/70) to afford 2,4-dichloro-6-(2-(isopropylsulfonyl)phenylamino)pyrimidine-5-carbaldehyde. MS (ES+): 374.0 (MH+).
