Participants

Reaction Steps

A mixture of 200 mg (1.30 mmol) of 4-chloro-7H-pyrrolo[2,3-d]pyrimidine (prepared by the method of Davoll, J. Am. Chem. Soc., (1960). 82, 131), the product from Method A (589 mg/5.21 mmol) and 3 mL of tert-butanol was stirred in a sealed tube at 100° C. for 24 h. The reaction mixture was added to water, acidified to pH 1 with 1 N HCl (aq), washed twice with diethylether (ether) and basified to pH 14 with 1 N sodium hydroxide (NaOH). The resulting precipitate was filtered and dried in vacuo to obtain 263 mg (88%) of the title compound, mp 177-180° C. 1H NMR (400 MHz, CDCl3): δ1.11-1.22 (m, 1H), 1.43-1.63 (m, 4H), 1.73 (br d, 1H, J=13.3 Hz), 1.83-1.90 (m, 4 H), 3.23 (s, 3H), 4.69 (br, 1H), 6.53 (d, 1H, J=3.5 Hz), 7.03 (d, 1H, J=3.5 Hz), 8.30 (s, 1H), 10.6 (br, 1H). LRMS: 231 (M+1).
