BP (2 3 mg. 0.01 5 miiiol). ; i n J ADC (ca. 2 mg. 0.009 mmol) in 5 mL of MeCN/MeOH (3 .?) was irr;idi;ited over : I period of 2 25 h (2. > 345 nm). In analogy to the synthesis of 8 more Kniethyl maleimide was added at 45 min intervals ( 2 x 4 mg. altogether 0.1 I inmttl). The reactioiis werc x;ded up successfully; however. w hen the very reactive ,V-methyl inalciniiJe w i i h used [addition compounds 7. 8. and 9). the reaction conditions had to be reoptiinimi
