Add a solution of acetyl chloride (0.15 mL, 2.1 mmol) in absolute ethanol at ambient temperature to (S)-2-Butyl-10-(4-methyl-3-phenethyl-piperazin-1-yl)-4H-3-thia-1,4,9-triaza-benzo[f]azulene (0.19 g, 0.41 mmol) in absolute ethanol, with added drops of methanol to solubilize the freebase, and concentrate under reduced pressure gives the title compound (0.18 g). Mass spectrum (APCI+, m/e): 460 (M+1−2HCl); exact mass spectrum (ES+, m/e, C27H33N5S.2HCl): calc. 460.2535 (M+1−2HCl), found 460.2556.
