実験手順

(ii-2) A mixture of 7.0 g (0.026 mol) of Compound (VI) [R2 =CH3, R3 =CN], 6 ml of triethylamine, 15 ml of tert-butylamine, 0.1 g of sodium bromide micro-powder, 2.8 g of anhydrous sodium carbonate or potassium carbonate, 30 ml of anhydrous ethanol, and 100 ml of methyl ethyl ketone was reacted at 95° C. in an oil bath for 8 hours while stirring. The reaction solution was filtered while it was warm. The filtrate was purified using chromatography according to the same method as above to obtain Compound (I) [R1 =C(CH3)3, R2 =CH3, R3 =CN] at a yield of 78.5%.
