Procedure:
To a flame dried round bottom flask under N2 was added 4-chloropyrazolo[3,4-d]pyrimidine (J. Am. Chem. Soc. 1956, 78, 784) (1.80 g, 11.65 mmol), t-butyl 4-hydroxy-1-piperidinecarboxylate (2.46 g, 12.23 mol), and PS—PPh3 (9.21 g, 1.77 mmol/g) in anhydrous tetrahydrofuran (200 mL). The mixture was cooled to 0° C. and diethyl azodicarboxylate (DEAD) (2.20 mL, 13.98 mmol) in tetrahydrofuran (20 mL) was added dropwise. The mixture was allowed to warm to room temperature and stirred overnight. The reaction was then filtered and taken up in methylene chloride. The insoluble material was filtered off. The filtrate was concentrated, taken up in methylene chloride, and put in the freezer for 5 hr. The crystals that formed were filtered off and the filtrate was purified by silica gel chromatography (0-2% methanol/methylene chloride) to give pure tert-butyl 4-(4-chloro-1H-pyrazolo[3,4-d]pyrimidin-1-yl)piperidine-1-carboxylate. 1H-NMR (500 MHz, CDCl3) δ 8.76 (s, 1H), 8.16 (s, 1H), 4.92-5.02 (m, 1H), 4.32 (br s, 2H), 2.97 (br s, 2H), 2.20-2.31 (m, 2H), 1.96-2.05 (m, 2H).

Procedure:
2,2,3,4,4,4-hexafluorobutan-1-ol (202 g, 1.1 mol, obtained from Sinochem Corp., Beijing, China), 1,1,2,2,3,3,4,4,4-nonafluorobutane-1-sulfonyl fluoride (332 g, 1.1 mol, obtained from 3M Company of Saint Paul, Minn.) and water (300 g) were combined in a 3-L, 3-necked round bottom flask. The flask was equipped with a magnetic stirrer, cold water condenser, thermocouple and a 250-mL addition funnel. Aqueous potassium hydroxide (149.3 g, 45 weight percent, 1.22 equivalents) was added dropwise via an addition funnel at such a rate that the temperature did not exceed 35° C. Once the addition of the base was complete the mixture was stirred for 16 hours at room temperature. The precipitated salts were then filtered from the mixture and the lower liquid fluorochemical product phase was separated from the upper aqueous phase. Unreacted 2,2,3,4,4,4-hexafluorobutan-1-ol and 1,1,2,2,3,3,4,4,4-nonafluorobutane-1-sulfonyl fluoride were removed by atmospheric distillation.
