Procedure

The obtained (S)-4-(benzyloxycarbonylamino)-N-(1-hydroxymethylpyrrolo[2,3-b]pyridin-4-yl)thiochromane-7-carboxamide (766 mg) was dissolved in methanol (10 ml) and tetrahydrofuran (20 ml), and an aqueous solution (30 ml) of sodium acetate (5.00 g) was added. The reaction mixture was stirred under reflux for 5 hr and allowed to return to room temperature. Water (100 ml) was added and the precipitated crystals were collected by filtration to give the objective (S)-4-(benzyloxycarbonylamino)-N-(1H-pyrrolo[2,3-b]pyridin-4-yl)thiochromane-7-carboxamide (504 mg) as a pale yellow solid.
