309956-78-3, (R)-tert-Butyl piperidin-3-ylcarbamate is a piperidines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

EXAMPLE II 3-Methyl-7-(2-butyn-1-yl)-8-[(R)-3-(tert.-butyloxycarbonylamino)-piperidin-1-yl]-xanthine 11.00 g of (R)-3-tert.-butyloxycarbonylamino-piperidine are added to 15.00 g of 3-methyl-7-(2-butyn-1-yl)-8-bromo-xanthine and 16.00 g of potassium carbonate in 100 ml of dimethylsulphoxide and the thick, light beige suspension is stirred for four hours with a mechanical stirrer at approx. 114 C. Then another 900 mg of (R)-3-tert.-butyloxycarbonylamino-piperidine, dissolved in 10 ml of dimethylsulphoxide, are added to the reaction mixture and this is stirred for a further two hours at 114 C. After cooling to ambient temperature the reaction mixture is diluted with copious amounts of water. The precipitate formed is thoroughly triturated until no more clumps are left, and suction filtered. The light solid is again suspended with water, suction filtered, washed with water and diethyl ether and dried in the circulating air dryer at 60 C. Yield: 19.73 g (94% of theory) Rf value: 0.64 (silica gel, ethyl acetate) Mass spectrum (ESI+): m/z=417 [M+H]+

As the paragraph descriping shows that 309956-78-3 is playing an increasingly important role.
