Reaction Steps

To a solution of 500 mg (2.4 mmol) of 2,4,6-trichloro-5-cyano-pyrimidine in 30 ml of dioxane were added at room temperature 0.84 ml (4.8 mmol) of N-ethyl-diisopropylamine and 0.52 ml (7.2 mmol) of cyclopropylamine. The yellow reaction mixture was stirred at room temperature during 18 hours, then, for working-up, it was evaporated under reduced pressure. The residue obtained was then chromatographed on silica gel using a 3:1 mixture of dichloromethane and hexane as the eluent yielding 328 mg (1.3 mmol, 55% of theory) of 4-chloro-2,6-bis-cyclopropylamino-pyrimidine-5-carbonitrile as a yellow solid; MS: [M+H]+=249.
