Versuchsvorschrift

A solution of ethyl 9-(6-oxo-2,3-di-p-tolyl-7,8-dihydropyrido[2,3-b]pyrazin-5(6H)-yl)nonanoate (step 1)(392.5 mg, 0.764 mmol) in MeOH (10 ml) was treated with 1M NaOH (2.292 ml, 2.292 mmol) and stirred at RT overnight. The mixture was concentrated under reduced pressure to remove MeOH and acidified using 1M HCl. The resulting mixture was extracted with DCM and the organic extracts were concentrated under reduced pressure to afford the titled compound;
