Versuchsvorschrift

To a solution of [2-(4-methoxyphenyl)-[1,3]-dioxolan-2-yl]methylamine (Preparation 45, 0.117 g, 0.56 mmol) in dichloromethane (5 mL) was added DIPEA (213 μL, 1.22 mmol), 5-chloro-1H-pyrrolo[2,3-c]pyridine-2-carboxylic acid (Preparation 18, 0.100 g, 0.51 mmol) and HOBT (0.076 g, 0.56 mmol). The resulting solution was stirred for 2 min then EDCI (0.117 g, 0.61 mmol) was added and stirring was continued for 18 h at rt. The reaction mixture was partitioned between dichloromethane (30 mL) and water (20 mL) and the layers separated. The aqueous phase was extracted with dichloromethane (3×20 mL) then the combined organics were washed with brine (20 mL), dried (MgSO4), filtered and concentrated in vacuo. Recrystallisation from methanol/dichloromethane gave the title compound as an orange solid. δH (CDCl3): 3.81 (3H, s), 3.84-3.91 (4H, m), 4.05 (2H, m), 6.56 (1H, t), 6.76 (1H,s), 6.89 (2H, d), 7.44 (2H, d), 7.57 (1H, s), 8.68 (1H, s), 9.94 (1H, br s).
