Versuchsvorschrift

Gaseous ammonia (from a lecture bottle) was bubbled into a suspension of cis-[3-(4-chloro-5-iodopyrrolo[2,3-d]pyrimidin-7-yl)-cyclobutyl]-methanol (406.8 mg, 1.12 mmol) in dioxane (10 mL) and iPrOH (10 mL) in a Parr bomb, cooled by dry ice/acetone, for 5 min, then the vessel was sealed and heated to 90° C. overnight. LC/MS after 17 h indicated incomplete conversion. More ammonia was bubbled into the mixture, and heating to 90° C. was continued. After 1 d, conversion was complete. The solvents were evaporated, water was added to the residue, and the pale yellow solid was filtered off and dried in vacuo to give the title compound as a pale yellow solid. The compound was used in the next step without further purification. The aqueous filtrate was extracted with CH2Cl2 (3×20 mL), the combined extracts were dried over MgSO4, filtered and concentrated to give a yellow oil that slowly solidified. Purification by HPLC gave analytically pure material. 1H NMR (CDCl3, 400 MHz): δ=2.40-2.57 (m, 4H), 2.57-2.66 (m, 2H), 3.73 (d, J=4.4 Hz, 2H), 5.03 (quint, J=8.4 Hz, 1H), 5.62 (brs, 2H), 7.21 (s, 1H), 8.26 (s, 1H). 13C NMR (DMSO-d6, 100.6 MHz, DEPT135): δ=29.96 (+), 32.70 (2C, −), 44.42 (+), 50.25 (Cquart), 64.16 (−), 102.98 (Cquart), 126.94 (+), 149.41 (Cquart), 151.72 (+), 157.13 (Cquart). MS (ES+): m/z 345.0 (100) [MH+]. HPLC: tR=1.7 min (OpenLynx, polar—5 min). C11H131IN4O.⅔H2O: C: calc. 37.10. found 36.92; H: calc. 4.06. found 3.88; N: calc. 15.73. found 16.07.
