Reaction Steps

To a slurry of N-(1-carbamoyl-1,2-dimethylpropyl)-2-quinolinecarboxamide (16.04 g, 0.0562 mol) in xylene (610 ml) under nitrogen is added a 50% oil dispersion of sodium hydride (2.7 g, 0.056 mol) at 20° C. The reaction is heated to reflux for 2 hours, cooled and water (50 ml) added. The aqueous layer is extracted with methylene chloride and the organic layers combined and evaporated to give a yellow oil, 17 g. Purification is accomplished by passing through a silica gel column using hexane-ethyl acetate as solvent. A pale yellow solid is obtained and is recrystalized from ethyl acetate to give 11.77 g (78%) of white product, mp 112°-117° C. Anal. calcd. for C16H17N3O: C, 71.88; H, 6.41; N, 15.72. Found: C, 71.91; H, 6.47; N, 15.70.
