Procedure

The amine (27) (66 mg) in dry dichloromethane (5 ml) was cooled to 0° and treated with pyridine (49 mg) followed by formic-acetic anhydride (27 mg). The mixture was stirred at 0° for 15 minutes then allowed to warm to room temperature over 15 minutes, and evaporated to dryness. The residue was chromatographed on silica gel to give the product (28) (53 mg).
