実験手順
By utilizing the well known method, 1-[(1,3-benzothiazol-2-yl)methyl]-3-methyl-7-(2-butyn-1-yl)-8-bromo-xanthine 2b (400 mg, 0.9 mmol) was dissolved in N,N-dimethylformamide (6 ml). (R)-3-tert-butoxycarbonyl-aminopiperidine (180 mg, 0.9 mmol) and potassium carbonate (186.5 mg, 1.35 mmol) were added to give a reaction mixture. The reaction mixture was reacted at 75° C. for 2 hours, and TLC was used to monitor the reaction progress. After the reaction was completed, the obtained reaction mixture was cooled to room temperature. The cooled reaction solution was poured into water, suction filtered, and the obtained solid was washed with water, dried to give 1-[(1,3-benzothiazol-2-yl)methyl]-3-methyl-7-(2-butyn-1-yl)-8-[(R)-3-tert-butoxycarbonyl-amino-piperidin-1-yl]-xanthine 2c (460 mg, yellow solid), yield: 90.8%.
