反応手順
In a 50 mL round bottom flask, dissolved 4-(4-methylpiperazin-1-yl)benzoic acid (1.00 g, 4.50 mmol) in dichloromethane (5.0 mL). Added oxalyl chloride (1.2 mL, 9.1 mmol) and N,N-dimethylformamide (2 drops). Stirred at RT for 2 hours. Concentrated and isolated 4-(4-methylpiperazin-1-yl)benzoyl chloride as an off-white solid. LC/MS of methyl ester (quenched with methanol) revealed an MS (M+H)+ of 235; Calc'd 234.29 for C13H18N2O2 (methyl ester).
