The obtained residue waspurified by silica gel chromatography (hexane : ethyl acetate) to obtain a product of interest (6.51 g, yield: 75%).1H NMR(CDCl3) delta: 6.56 - 6.51 (m, 1H), 4.58 - 4.41 (m, 1H), 3.80 - 3.62 (m, 1H),2.58 - 2.41 (m, 1H), 2.31 - 2.13 (m, 2H),1.98 - 1.77 (m, 2H), 1.54 - 1.47 (m, 1H), 1.44 (s, 9H), 1.25 (s, 12H)ESI-MS m/z 324(MH+)

YieldReaction ConditionsOperation in experiment
With potassium phosphate; dichloro(1,1'-bis(diphenylphosphanyl)ferrocene)palladium(II)*CH2Cl2; In 1,4-dioxane; water; at 100℃; for 14h;Inert atmosphere; To 4-chloro-7H-pyrrolo[2,3-d]pyrimidin (2.97 g), the compound (9.39 g) of Reference Example 1(2a) and tripotassiumphosphate (10.2 g), 1,4-dioxane (66 mL) and water (11 mL) were added, followed by nitrogen substitution, andPdCl2(dppf)CH2Cl2 (1.41 g) was then added to the reaction mixture. The thus obtained mixture was stirred at 100C for14 hours. Thereafter, the reaction mixture was cooled to a room temperature, and ethyl acetate and water were thenadded to the mixture. Thereafter, the thus obtained mixture was filtered through Celite. The filtrate was then extractedwith ethyl acetate, and the gathered organic layer was then washed with water and then with a saturated saline. Theresultant was dried over anhydrous sodium sulfate, and was then concentrated under a reduced pressure. The obtainedresidue was purified by silica gel chromatography (chloroform : methanol) to obtain tert-butyl (3-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)cyclohex-3-en-1-yl)carbamate. The above obtained compound was used in the subsequent reaction withoutfurther purification.
