Procedure

The procedure of Example 1 was repeated using 2-(3-nitrophenylamino)nicotinaldehyde (1.0 eq.), ethyl 5-(pyrazin-2-yl)pentanoate (1.5 eq., prepared in Synthetic Example 7) and LDA (1.5 eq.) to obtain 1-(3-nitrophenyl)-3-[3-(pyrazin-2-yl)propyl]-1,8-naphthyridin-2(1H)-one (yield, 33%). The product was purified through flash column chromatography and recrystallization (mp 194–195° C./DMF).
