Reaction Steps
A 500 mg sample of 5-chloro-3-(N-t-butoxycarbonyl-2-(S)-azetidinylmethoxy)pyridine, prepared as in Example 39a above, was dissolved in 3 mL of 37% HCHO and 1.5 mL of HCOOH, and the reaction mixture was stirred at 100° C. for 40 minutes. The reaction was quenched by addition of H2O. The mixture was adjusted to pH 7 with NaHCO3 and extracted with methylene chloride, the extract was dried over MgSO4, and the solvent was removed to give the title compound (181 mg).
