Reaction Steps

A suspension of 5-cyano-4-methyl-7-azaindole (48 mg, 0.31 mmol) and 10% palladium on carbon (25 mg) in methanol (10 mL) and concentrated HCl (0.5 mL) was shaken on a Parr apparatus under hydrogen (50 psi) for 6 h. The mixture was filtered through celite and evaporated in vacuo. The residue was dissolved in a minimum volume of methanol, ether was added and the solids collected by filtration to give the title compound as a pale yellow solid:
