Reaction Steps
Dioxane hydrochloride (3 mL) was added to 7-[3-(4-methyl-pyridin-3-yl)-2-oxo-imidazolidin-1-yl]-2-oxo-3,4-dihydro-2H-quinoline-1-carboxylic acid tert-butyl ester (0.145 g, 0.00034 mol) at 0° C. The resulting reaction mixture was stirred at room temperature for 2 hours. The reaction was monitored by TLC (40% ethylacetate in hexane). Purification by preparative HPLC, followed by column chromatography on silica gel (5% MeOH in CHCl3) afforded 48 mg of the product (35.47% yield).
