Versuchsvorschrift

A solution of 70.25 mg (0.25 mmol) of (-)-9,10-difluoro-3(S)-methyl-7-oxo-2,3-dihydro-7H-pyrido[1,2,3-de]-1,4-benzoxazine-6-carboxylic acid and 141 mg (0.75 mmol) of 3-(4-methyl-1,2,3-triazol-1-yl)pyrrolidine hydrochloride in 3 ml of acetonitrile in the presence of 152.24 mg (1 mmol) of DBU was refluxed for 3 days under nitrogen atmosphere. The suspension was then evaporated and water was added to the residue and solid collected and washed with methanol to yield after drying 50 mg of the desired product, m.p. 241°-242° C. 1H NMR (TFA) δ: 9.16 (s, 1H), 8.37 (s, 1H), 7.99 (d, 13.3Hz, 1H), 5.75-5.6 (m, 1H), 5.15-4.1 (m, 7H), 3-2.6 (m, 2H), 2.67 (s , 3H), 1.8 (d, 6.8Hz, 3H). Anal. calcd. for C20H20FN5O4 . 1/2 H2O: C, 56.87; H, 5.01; N, 16.58. Found: C, 57.30; H, 4.77; N, 16.75.
