A mixture of 2.96 g (10 mmole) of 8-amino-9,10-difluoro-3-methyl-7-oxo-2,3-dihydro-7H-pyrido [1,2,3-de][1,4]benzoxazine-6-carboxylic acid, 2.1 g (15 mmole) of N-cyclopropyl-3-pyrrolidinemethanamine, 3.03 g (30 mmole) of triethylamine and 100 ml of N,N-dimethylformamide is heated at 100° C. for four hours. The solvent is removed in vacuo and the residue triturated with water. The aqueous suspension is adjusted to pH 7.2 with 1.0M hydrochloric acid. The solid is removed by filtration, washed with water, and dried in vacuo to give 8-amino-9-fluoro-3-methyl-10-[(3-cyclopropylaminomethyl)-1-pyrrolidinyl]-7-oxo-2,3-dihydro-7H-pyrido[1,2,3-de][1,4]benzoxazine-6-carboxylic acid.
