Procedure

Combine (S)-2-(2-naphthalen-1-yl-ethyl)-piperazine (720 mg, 3.0 mmol), 2-methyl-4H-3-thia-4,9-diaza-benzo[f]azulen-10-ylamine (686 mg, 3.0 mmol), toluene (6 mL), DMSO (1.5 mL) and glacial acetic acid (1 drop). Heat at 105° C. After 48 h, cool to ambient temperature and dilute with ethyl acetate and water. Extract with ethyl acetate. Wash the extracts with water and brine, dry over sodium sulfate, filter and concentrate the filtrate. Purify by silica gel chromatography using 2N ammonia in methanol-methylene chloride (2.5%–3%) as the eluent to give 290 mg (21%)of the title compound: mass spectrum (ion spray): m/z=453 (M+1), 451 (M−1).
