Methylamine (24% w/v in H2O, 5 mL) was added to MNR 99-3 (175 mg, 0.7 mmol),. The mixture was stirred at 85 ˚C overnight.

Reaction mixture was cooled to room temperature and then water (20 mL) was added and the product was extracted with EtOAc (3 x 20 mL). The combined organic layers were washed with brine, dried (MgSO4), filtered and evaporated to give a yellow solid. 1H NMR showed desired product along with some impurities.
