YieldReaction ConditionsOperation in experiment
In ethanol; for 2h;Reflux; General procedure: Thiourea (7 mmol) was dissolved in 13.5 mL ethanol and the appropriate alkylbromide (7 mmol) was added. The mixture was stirred and heated under reflux for 2 h after which the reaction became homogenous. The reaction was allowed to cool to room temperature and the ethanol solvent was removed under reduced pressure. A solution of NaOH (10.5 mmol) in 8.75 mL water was added to the residue, and the reaction mixture was heated under reflux (120 C) for 2 h. The reaction was subsequently cooled to room temperature and aqueous H2SO4 (15%) was added. The mercaptan separated as oil droplets and was extracted to diethylether (30 mL). The organic phase was washed twice with water, dried over anhydrous Na2SO4 and removed under reduced pressure. This yielded the desired mercaptans which were used without further purification for the synthesis of 1, 3 and 4.

YieldReaction ConditionsOperation in experiment
20% With potassium carbonate; In N,N-dimethyl-formamide; at 90℃; for 1.5h;Microwave irradiation; Example 15: Preparation of 8-[2-(3-chlorophenyl)ethyl]-3-methyl-4-({4-[3-(trifluoromethyl)phenyl]piperazin-1-yl}carbonyl)-1-oxa-8-azaspiro[4.5]dec-3-en-2-one [Show Image] A mixture of 3-methyl-4-({4-[3-(trifluoromethyl)phenyl]piperazin-1-yl}carbonyl)-1-oxa-8-azaspiro[4.5]dec-3-en-2-one dihydrochloride (Example 1, 200 mg, 0.40 mmol), anhydrous potassium carbonate (180 mg, 1.30 mmol) and 1-(2-bromo-ethyl)-3-chlorobenzene (0.07 mL, 0.22 mmol) in anhydrous N,N-dimethylformamide (3 mL) was heated at 90C for 1.5 hours under microwave irradiation. The reaction mixture was concentrated under vacuum. The residue was taken up in dichloromethane (20 mL), washed with water (20 mL) and brine (20 mL), dried (MgSO4) and concentrated under vacuum. After purification by flash chromatography (silica), the title compound was obtained as a white solid (44 mg, 20%). 1H NMR (DMSO-d6, 400 MHz): delta 7.46-7.42 (m, 1 H), 7.30-7.17 (m, 6H), 7.11 (d, J = 7.5 Hz, 1H), 3.79-3.78 (m, 1H), 3.68-3.67 (m, 1H), 3.55 (s, 3H), 3.55 (d, J = 4.9 Hz, 2H), 2.89-2.88 (m, 3H), 2.73-2.71 (m, 2H), 2.49-2.48 (m, 2H), 2.23-2.21 (m, 3H), 1.82-1.81 (m, 1H), 1.75 (s, 3H), 1.67-1.66 (m, 1H), 1.51-1.49 (d, J = 7.3 Hz, 1H).
