Procedure

A mixture of 3-[(3-benzyloxy-2-methyl-phenyl)-methoxy-methyl]-1H-pyrrolo[2,3-b]pyridine (625, 24 mg, 0.067 mmol), trifluoroacetic acid (1 mL, 13 mmol), and triethylsilane (2 mL, 12.5 mmol) in acetonitrile (10 mL) was refluxed for 4 hours. The mixture was concentrated and the residue was dissolved in ethyl acetate. The solution was washed with saturated sodium bicarbonate, brine, and dried over sodium sulfate. After removal of solvent, the residue was washed with a mixture of ethyl ether and hexanes (1:1) to provide the compound as a yellow solid (P-1857, 17 mg, 75%). MS (ESI) [M+H+]+=329.24.
