Procedure:
This example illustrates a synthesis of 1-(3-(R)-methyl-7-methyl-6,7-oxidooctyl)-3,7-dimethylxanthine (inventive compound no. 1588R). Sodium hydride(95%) (631 mg, 25 mmol) was added to a solution of theobromine (4.14 g, 23 mmol) in dimethylsulfoxide (75 mL). After 20 minutes of stirring, (R)(-)Citronellyl bromide (5.0 g, 22.8 mmol) was added. After 16 hours of stirring at room temperature, the reaction was poured into a separatory funnel containing 500 mL of water and extracted with dichloromethane (3×100 mL). The organic extracts were combined, washed with water (100 mL) and brine (100 mL), dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The crude product obtained was further purified by flash chromatography over silica gel using 30% petroleum ether/ethyl acetate eluant, yielding 5.9 g (81.5% yield) 1-(3-(R)-methyl-7-methyloct-6-enyl)-3,7-dimethylxanthine (inventive compound no. 1596R) as a yellowish oil. A solution of 1-(3-(R)-methyl-7-methyloct-6-enyl)-3,7-dimethylxanthine (318 mg, 1 mmol) and m-chloroperoxybenzoic acid (0.52 g; 1.5 mmol) (50% by wt) in dichloromethane (7 mL) was stirred for 5 hours. The reaction mixture was diluted with 40 mL of dichloromethane and washed successively with 20% aqueous sodium sulphite solution (10 mL), saturated sodium bicarbonate solution (10 mL), water and brine solutions. The organic layer was dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The crude product obtained was further purified by flash chromatography over silica gel using 5% petroleum ether/ethyl acetate eluant, yielding 0.253 g (76% yield) of 1-(3-(R)-methyl-7-methyl-6,7-oxidooctyl)-3,7-dimethylxanthine.

Procedure:
Subsequently, to a solution of 3-t-butyldiphenylsilyloxy-1-(4-ethoxycarbonyl-1,3-thiazol-2-yl)azetidine (1.16 g, 2.49 mmol) (obtained as described in Reference Example 2(1)) in benzene (8.5 ml) was added a solution of 0.67M 2-(t-butyldiphenylsilyloxy)ethylamine-trimethylaluminium in benzene (6.42 ml) at room temperature under an atmosphere of nitrogen. The mixture was heated under reflux for 5 hours. After checking the completion of the reaction, 10% aqueous acetic acid solution (50 ml) and ethyl acetate (200 ml) were added to the reaction mixture, and the resulting mixture was stirred at room temperature for 1 hour. After adding ethyl acetate thereto, the reaction mixture was partitioned between ethyl acetate and water. The organic layer was washed successively with saturated aqueous sodium hydrogencarbonate solution and saturated aqueous sodium chloride solution, dried over anhydrous sodium sulfate, filtered and concentrated under reduced pressure. The residue was purified by chromatography on a silica gel column using hexane:ethyl acetate (3:1) as the eluant to afford 3-t-butyldiphenylsilyloxy-1-{4-[2-(t-butyldiphenylsilyloxy)ethylcarbamoyl]-1,3-thiazol-2-yl}azetidine (1.68 g, yield 94%) as a pale brown solid.
