Procedure

Azetidine hydrochloride (10 mg, 0.11 mmol) was added to a stirred solution of 2-(3-formylphenyl)-N-{5-[(7-isopropyl-7H-pyrrolo[2,3-d]pyrimidin-5-yl)carbonyl]pyridin-3-yl}acetamide (Preparation 192, 23 mg, 0.05 mmol) in DCM (1 mL) and acetic acid (0.04 mL, 0.60 mmol). The reaction mixture was stirred for 30 min at room temperature before addition of sodium triacetoxyborohydride (29 mg, 0.14 mmol) and stirring continued for 3 hours. Water (1 mL) was added and the mixture concentrated in vacuo (with toluene azeotroping). The residue was purified by preparative HPLC to afford the title compound as a formate salt in 12% yield, 3.4 mg.
