Reaction Steps

A solution of (1R)-1-[(4-isocyanato-4-methyl-1-piperidinyl)methyl]-1,2,5,6-tetrahydro-4H,9H-imidazo[1,2,3-ij]-1,8-naphthyridine-4,9-dione (561 mg, 1.638 mmol) in THF (10 ml) and water (10.00 ml) at rt was treated with sodium hydroxide (5 ml, 10.00 mmol), and stirred at rt for 1 h. Reaction was then treated with concentrated HCl (5 ml, 12M) and stirred at rt for 18 h, then evaporated. The resultant solid was treated with methanol (20 ml) and then the solvent was decanted from the solid and evaporated to give the product as an impure green solid (687 mg, 108%).
