Reaction Conditions

Reaction Steps

Following the method of Example 380 using 8-fluoro-11H-12-thia-6,11-diaza-dibenzo[a,f]azulen-5-ylamine hydrochloride (0.40 g, 1.3 mmol) and (S)-2-(2-methoxy-ethyl)-piperazine (0.36 g, 2.5 mmol), stirring at 115° C. for 24 hours, wash the separated organic layer with 0.1 N NaOH (2×), and extract the combined aqueous layers with ethyl acetate. Combine the organics and wash with a saturated solution of sodium chloride (3×), and then dry (sodium sulfate), filter, and concentrate under reduced pressure to a residue. Purify the residue by flash chromatography, eluting with a gradient of a solution of 5% 2M ammonia in methanol, in dichloromethane (in dichloromethane) to give the title compound (0.096 g). Mass spectrum (APCI+, m/e): 411 (M+1).
