Reaction Conditions

Reaction Steps

A 811 mg sample of 3-(1-BOC-2(S)-azetidinylmethoxy)-6-chloropyridazine, prepared as in Example 13a above, was dissolved in 10 mL of satd HCl in ethanol cooled to 0° C., and the reaction was stirred at room temperature for 16 hours. The solvent was removed under vacuum, and the oily residue was dried under high vacuum for 4 hours to provide a solid. The solid was triturated with ether, collected, and recrystallized three times from ethanol/ether to give 118 mg of the title compound. mp 150-151° C.
