Acetaldehyde → 1-{3-[4-Amino-7-(1-ethyl-piperidin-4-yl)-7H-pyrrolo[2,3-d]pyrimidine-5-carbonyl]-phenyl}-3-(3,5-dichloro-phenyl)-urea

Participants

Reaction Steps

A solution of 1-[3-(4-Amino-7-piperidin-4-yl-7H-pyrrolo[2,3-d]pyrimidine-5-carbonyl)-phenyl]-3-(3,5-dichloro-phenyl)-urea (100 mg, 0.19 mmol) and acetaldehyde (8.4 mg, 0.19 mmol) in DMF/THF (20%, 10 mL) was stirred for 30 minutes at room temperature. Sodium triacetoxyborohydride (61 mg, 0.29 mmol) was added to the reaction mixture, stirred for 3.5 hours, and concentrated in vacuo. Purification by reverse phase preparative HPLC (HPLC method 2) provided the title compound as a white solid (11 mg, 10%). MS: 553.5 (MH+); HPLC Rf: 1.7 min. (HPLC method 2); HPLC purity: 100%.
