Procedure
6.15 g (60 mmole) of acetic anhydride are mixed with a solution of 11.8 g (40 mmole) of 3-piperazino-2-phenyl-benzo(b)thiophene in 50 milliliters of methylene chloride and left for 2 hours at ambient temperature. After washing with dilute ammonia the organic phase is dried over Na2SO4 and evaporated: 13.2 g (98% of theory) of colourless needles, mp 167°-169° (CCl4).
