The alkylation of NAD(P) to N(1)-(2-aminoethyl)-NAD(P) with ethyleneimine in aqueous solution was optimized. First the pH-dependency of the alkylation of the N (1)-position of the adenine nucleus of NAD was studied in the pH range 2-5.5 at 20°C. followed by adjusting the temperature and the concentration of ethyleneimine to achieve acceptable reaction times. The results were directly applicable with respect to the synthesis of N(1)-(2-aminoethyl)-NADP.
