Reaction Steps

A solution of N-[(3R,4R)-1-benzyl-4-methylpiperidin-3-yl]-N-methyl-1-[2 -(trimethylsilyl)ethoxy]methyl-N-(1H-pyrrolo[2,3-b]pyridin-4-yl)-amine (0.065 g, 0.00014 mol) in trifluoroacetic acid (0.6 mL, 0.008 mol) and methylene chloride (3 mL, 0.05 mol) was stirred overnight. The solvent volume was reduced by roto-vap 3× azeotroped with MeOH. The resulting orange oil was stirred in methanol (1.5 mL, 0.037 mol) and 1.00 M of sodium hydroxide in water (0.5 mL) overnight. Solvents were removed under vacuum and the remaining solid was stirred in ethyl acetate and water. The organic phase was washed with sat. NaCl and the solvent was removed under vacuum to give 37 mg of an orange oil.
