Procedure

A degassed mixture of N-[(3R,4R)-1-benzyl-4-methylpiperidin-3-yl]-N-methyl-N-(1H-pyrrolo[2,3-b]pyridin-4-yl)-amine (0.030 g, 0.000090 mol) and palladium (0.028 g, 0.000026 mol) in ethanol (2 mL, 0.03 mol) and 3.0 M of hydrogen chloride in water (0.2 mL) was stirred under an atmosphere of hydrogen overnight. The reaction mixture was filtered and washed with MeOH. The solvent was removed under vacuum to give 52 mg of an orange viscous oil. The oil was partitioned between ethyl acetate and sat. NaHCO3. The aqueous phase was extracted with ethyl acetate and THF. The combined organic phases were washed with sat. NaCl. Solvents were removed under vacuum to give 47 mg of an orange solid. 1H NMR (400 MHz, MeOH): δ 7.8 (1H, d); 7.1 (1H, d); 6.6 (1H, d); 6.3 (1H, d); 4.45 (1H, m); 3.7 (1H, m); 3.12 (3H, s); 3.4-1.0 (6H, m); 1.1 (3H, d). MS (M+H)+: 245.
