实验步骤: To methyl 3-(hydroxymethyl)-5-methylbenzoate prepared by the method in EXAMPLE SP-198, Step 2 in anhydrous methylene chloride at −30° C. is added methanesulfonyl chloride (601 μL, 7.8 mmol), then triethylamine (1.5 mL, 11.1 mmol), and the reaction is stirred at 0° C. 15 min. The resulting precipitate is filtered, and the filtrate is added to N-methylisoamylamine (2.1 mL, 16.7 mmol). The reaction stirred at room temperature 16 h. The solution is concentrated under reduced pressure, redissolved in ethyl acetate and washed with saturated sodium bicarbonate, brine, dried (sodium sulfate), filtered, and concentrated under reduced pressure. Purification by flash column chromatography (silica, 20% ethyl acetate/hexanes) provides the title compound. ESI MS m/z 264.2 [M+H]+. 15 min The resulting precipitate is filtered The solution is concentrated under reduced pressure redissolved in ethyl acetate washed with saturated sodium bicarbonate, brine dried (sodium sulfate) filtered concentrated under reduced pressure Purification by flash column chromatography (silica, 20% ethyl acetate/hexanes)

实验步骤: Following Example 216, to a well stirred solution of 8-(1H-Pyrazol-4-yl)-4,5-dihydro-6-oxa-3-thia-1-aza-benzo[e]azulene-2-carboxylic acid and N,3-dimethylbutan-1-amine to give 255. MS: (ESI+)=397.1
