实验步骤: cis-13-Octadecen-2-yn-1-ol was synthesized in the following manner. Thus, 153 g (0.81 mole) of 8-bromo-1-octyne were added dropwise at 50° to 55° C. to 1 mole of methyl magnesium chloride dissolved in 300 ml of tetrahydrofuran and the mixture was agitated for 1 hour followed by the addition of 2 g of dilithium tetrachlorocuprate Li2CuCl4. Thereafter, a solution of 1 mole of cis-4-nonenyl magnesium chloride dissolved in 300 ml of tetrahydrofuran was added dropwise to the reaction mixture at 40° to 55° C. and the mixture was agitated for 4 hours at 48° C. was added dropwise to the reaction mixture at 40° to 55° C. the mixture was agitated for 4 hours at 48° C.

实验步骤: 8-Bromo-1-octyne (2.0 g, 10.6 mmol) prepared in step 1) was added to a dehydrated dimethylformamide (25 mL) solution containing 6-(thien-2-yl)-2-amino purine (1.2 g, 5.5 mmol) and potassium carbonate (2.3 g, 16.5 mmol), followed by stirring at room temperature for 15 hours. The reaction solution was concentrated and was separated between ethyl acetate and water. The organic layer was washed with saturated brine, was dried over anhydrous sodium sulfate, and was purified by medium-pressure preparative column chromatography to yield 6-(thien-2-yl)-9-(7-octynyl)-2-amino purine (1.6 g, 4.9 mmol, 87%). The reaction solution was concentrated was separated between ethyl acetate and water The organic layer was washed with saturated brine was dried over anhydrous sodium sulfate was purified by medium-pressure preparative column chromatography
