Reaction Steps

Enantiomer 2 of Ethyl 7-(2-methyl-6,7-diphenyl-3,4-dihydro-1,8-naphthyridin-1(2H)-yl)heptanoate (37 mg, 0.081 mmol) was dissolved in THF/water (1 ml/2:1) and lithium hydroxide (9.70 mg, 0.405 mmol) was added. The mixture was stirred at room temperature for 4 days and then diluted with water (25 ml). The pH was adjusted to pH 5-6 using 1M HCl. The aqueous portion was extracted with EtOAc (2×20 ml) and the combined organics extracts were washed with brine, dried over MgSO4, filtered and evaporated to afford Enantiomer 1 of 7-(2-methyl-6,7-diphenyl-3,4-dihydro-1,8-naphthyridin-1(2H)-yl)heptanoic acid;
