Reaction Conditions

Reaction Steps

To a mixture of the compound obtained in example 1 (200 mg, 0.53 mol), acetamidine HCl (124.5 mg, 1.32 mmol) and sodium methoxide (98.3 mg, 1.85 mmol) in 7 ml of methanol was stirred at 60-70° C. for 18 hrs under nitrogen atmosphere. Once the reaction is complete, the reaction mass was evaporated under vacuum and the residue was diluted with ethyl acetate and water. The organic layer was washed with water followed by brine, dried over sodium sulfate and concentrated under vacuum. The crude product was purified by column chromatography to get 200 mg (40% yields) of the solid product. MP-more than 300° C.
