実験手順

6-[3,5-bis(trifluoromethyl)benzyl]-4-chloro-5,6,7,8,9,10-hexahydro-2-(methylthio)-5-oxopyrimido[4,5-b][1,5]diazocine(Compound of Reference Example 7; 1.50 g) was dissolved in N,N-dimethylformamide (6 mL). To this solution, sodium hydride (185 mg, 60% oil suspension) was added and the mixture was stirred at room temperature for 1 hour. Methyl iodide (0.4 mL) was then added and the mixture was further stirred at room temperature for 1 hour. The reaction mixture was diluted with ethyl acetate, was sequentially washed with water and a saturated aqueous solution of sodium chloride, and was then dried over anhydrous sodium sulfate. Following removal of the solvent, the residue was purified on a silica gel column-chromatography (ethyl acetate:hexane=1:1) to obtain 6-[3,5-bis(trifluoromethyl)benzyl]-4-chloro-5,6,7,8,9,10-hexahydro-10-methyl-2-(methylthio)-5-oxopyrimido[4,5-b][1,5]diazocine (1.36 g, 88%).
