Procedure

HONH2 (50% aqueous, 2 mL) was added to III (10 mg, 0.028 mmol) in DMF (0.5 mL) and MeOH (2 mL) at rt. The reaction mixture was stirred for 17 h, after which the solvents were evaporated under reduced pressure. The resulting residue was dissolved and co-evaporated with toluene (2×2 mL) then was purified by silica gel column chromatography eluting with CH2Cl2/MeOH (100:3 to 100:10) to furnish IV as a colourless oil (8 mg, 84%).
