反応手順
400 mg of 1-cyclopropyl-6-fluoro-7-chloro-4-oxo-1,4-dihydro[1,8]naphthyridine-3-carboxylic acid and 84 g of t-butyl 8-(methoxyimino)-2,6diazaspiro[3,4]octane-2-carboxylate were added to 10 ml of acetonitrile and the resulting mixture was stirred for 3 hours at 45-50° C. Then the precipitated solid was filtered and dried to give 650 mg of the titled compound(yield: 93.9%).
