It is a common heterocyclic compound, the naphthyridine compound, Ethyl 7-chloro-1-cyclopropyl-6-fluoro-4-oxo-1,4-dihydro-1,8-naphthyridine-3-carboxylate, cas is 96568-07-9 its synthesis route is as follows.,96568-07-9
EXAMPLE 61 Ethyl (1’SR,2’SR,6’RS)-1-cyclopropyl-6-fluoro-1,4-dihydro-7-(2′-methylamino-8′-azabicyclo[4.3.0]non-4′-en-8′-yl)-4-oxo-1,8-naphthyridine-3-carboxylate STR201 The title compound is obtained by reacting ethyl 7-chloro-1-cyclopropyl-6-fluoro-1,4-dihydro-4-oxo-1,8-naphthyridine-3-carboxylate with the title compound from Example O, as described in Example 52. The hydrochloride is obtained by treating the product with a little dilute hydrochloric acid. Yield: 91% of theory. Rf =0.64 (methanol/dichloromethane/conc. ammonia 15:4:0.5).
With the complex challenges of chemical substances, we look forward to future research findings about Ethyl 7-chloro-1-cyclopropyl-6-fluoro-4-oxo-1,4-dihydro-1,8-naphthyridine-3-carboxylate
