Procedure

Gaseous ammonia was bubbled into an'PrOH (1 mL) solution of cis-4-(4-chloro-5-iodo-pyrrolo[2,3-d]pyrimidin-7-yl)-cyclohexanecarboxylic acid ethyl ester (30 mg, 70% pure by HPLC peak area, 0.048 mmol) in a glass pressure tube, cooled to −78° C. in a dry ice/acetone bath, for 15 min. The tube was equipped with a Teflon washer, sealed and heated to 110° C. for 7 h. After that time, the excess NH3 and the solvent were evaporated. The residue was used for the next reaction without purification. A portion of above crude material were purified by HPLC to give the title compound as pale yellow oil. 1H NMR (CDCl3, 400 MHz): δ=1.31 (t, 3H, J=7.6 Hz), 1.63-1.98 (m, 6 H), 2.29-2.35 (m, 2 H), 2.73 (m, 1 H), 4.22 (q, 2 H, J=7.6 Hz), 4.64-4.71 (m, 1 H), 5.58 (brs, 2 H), 7.11 (s, 1 H), 8.26 (s, 1 H). MS (ES+): 415.0 [MH+]. tR=2.7 min (polar—5 min).
