4-Bromo-2-methylaniline → HCID 67380949, compound

Participants

Reaction Steps

By reaction and treatment in the same manner as in Preparation Example 15 and using 4-bromo-2-methylaniline (3 g), N,N-bis(2-chloroethyl)-4-methylbenzenesulfonamide (5.65 g) and cyclopropylboronic acid (721 mg), 1-(4-cyclopropyl-2-methylphenyl)piperazine (640 mg) was obtained. To a solution (7 mL) of 6-bromonicotinic acid (132 mg) in methanol were added 1-(4-cyclopropyl-2-methylphenyl)piperazine (150 mg) and 4-(4,6-dimethoxy[1.3.5]triazin-2-yl)-4-methylmorpholinium chloride hydrate (DMT-MM) (217 mg), and the mixture was stirred at room temperature overnight. Water was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, and the solvent was evaporated. The residue was purified by column chromatography (ethyl acetate:hexane) to give the title compound (260 mg).
