실험 절차

9-(6-Oxo-2,3-di-p-tolyl-7,8-dihydropyrido[2,3-b]pyrazin-5(6H)-yl)nonanoic acid (Example 8) (200 mg, 0.412 mmol) in THF (10 ml) was stirred under N2 for 10 mins. Lithium pyrrolidinoborohydride (1M in THF) (2.059 ml, 2.059 mmol) was added carefully and the resulting mixture was stirred at RT for 1.5 hours. The reaction was quenched with 1M HCl and the mixture was concentrated under reduced pressure. The resulting mixture was extracted with DCM and the organic extracts were passed through a phase separating column. The organics were concentrated under reduced pressure and purification of the crude product by chromatography on silica eluting with 0-100% EtOAc in iso-hexane afforded the titled compound;
