Sodium hydride → 7-(4-Fluorophenyl)-2-{[4-(4-methylpiperazin-1-yl)-2-(propan-2-yloxy)phenyl]amino}thieno[3,2-d]pyrimidine-6-carboxamide

Participants

Reaction Steps

27 mg of sodium hydride (at 60%) are added to a solution of 126 mg of N-[4-(4-methylpiperazin-1-yl)-2-(propan-2-yloxy)phenyl]formamide in 2 ml of dimethylformamide. The suspension is stirred at ambient temperature for 30 min, and is then diluted with 1 ml of dimethylformamide, and a solution of 80 mg of 7-(4-fluorophenyl)-2-(methylsulfonyl)thieno[3,2-d]pyrimidine-6-carboxamide in 2 ml of dimethylformamide is added. The mixture is stirred at ambient temperature for 30 min, and then diluted with 50 ml of methanol. The mixture is stirred at ambient temperature for 1 h, and then concentrated under vacuum. The residue is purified on 40 g of silica, elution being carried out with 0-20% of methanol in dichloromethane, and then by high performance liquid chromatography (Macherey-Nagel 250×40 mm reverse phase C18 Nucleodur 10μ column. Eluent: MeCN containing 0.07% TFA and H2O containing 0.07% TFA. 10% MeCN hold: 3 min, gradient up to 95% MeCN in 37 min and then 95% MeCN hold of 8 min. Flow rate: 70 ml/min). The fractions containing the expected material are loaded on to a 2 g Varian Bond Elut SCX cartraige (preconditioned with MeOH). Washing the cartridge four times with methanol, followed by elution of the expected material with 2N ammonia in methanol gives, after drying, 10 mg of 7-(4-fluorophenyl)-2-{[4-(4-methylpiperazin-1-yl)-2-(propan-2-yloxy)phenyl]amino}thieno[3,2-d]pyrimidine-6-carboxamide.
