The invention discloses a preparation method of 2-bromine-6-fluoroanisole, the preparation method comprises the following specific steps: (1) carrying out electrophilic substitution reaction on 3, 4-difluoronitrobenzene and bromosuccinimide to generate a compound III; (2) reacting the compound III with sodium methoxide to generate a compound IV; (3) reducing the compound IV by sodium hydrosulfite to generate a compound V; (4) performing diazotization deamination on the compound V to generate a compound I; the obtained product is 2-bromo-6-fluoroanisole. The preparation method is higher in yield.

We report the synthesis of novel, potentially hypnotic fluorine-substituted phenyl acetate derivatives. We describe the structure-activity relationship that led us to the promising derivative: ethyl 2-(4-(2-(diethylamino)-2-oxoethoxy)-5-ethoxy-2-fluorophenyl) acetate (55). The unique pharmacological features of compound 55 are its relatively high affinity for the GABAA receptor, together with a unique affinity for the NMDA receptor, different to propanidid and AZD3043. In animal models, compound 55 showed stronger hypnotic potency and longer duration of LORR than propanidid and AZD3043, but also maintained a rapid recovery time to walking and behavioral recovery. In particular, compound 55 displayed reflex depression during infusion.

We describe the biological evaluation of isothiazoloquinolones (ITQs) having structural modifications at the 6-, 7-, and 8-positions. Addition of a methoxy substituent to C-8 effected an increase in antibacterial activity against methicillin-resistant Staphylococcus aureus (MRSA) and a decrease in cytotoxic activity against Hep2 cells. Removal of fluorine from C-6 or replacement of the C-8 carbon with a nitrogen compromised anti-MRSA activity. When the groups attached at C-7 were compared, the anti-MRSA activity decreased in the order 6-isoquinolinyl > 4-pyridinyl > 5-dihydroisoindolyl > 6-tetrahydroisoquinolinyl. The compound with the most desirable in vitro biological profile was 9-cyclopropyl-6-fluoro-8-methoxy-7-(2-methylpyridin-4-yl) -9H-isothiazolo[5,4-b]quinoline-3,4-dione (7g). This ITQ demonstrated (i) strong in vitro anti-MRSA activity (MIC90 = 0.5 μg/mL), (ii) strong inhibitory activities against S. aureus DNA gyrase and topoisomerase IV, with weak activity against human topoisomerase II, (iii) weak cytotoxic activities against three cell lines, and (iv) efficacy in an in vivo murine thigh model of infection employing MRSA.
