Reaktionsschritte
The 4-(N,N-dimethylaminomethyl) benzoyl chloride was prepared by reacting the acid with excess oxalyl chloride for 1 hr at 25° C. The 4-(N,N-dimethylaminomethyl) benzoic acid was in turn prepared from methyl 4-aminomethylbenzoate via reductive alkylation (CH2O, Na(OAc)3 BH as in J. Org. Chem., 1972, 37, 1673) followed by hydrolysis using 10% aqueous NaOH.
