To a 100-mL round-bottomed flask was added ethyl N-(diphenylmethylidene)-3-(2-methoxy-3-pyridinyl)alaninate (1.52 g, 3.91 mmol) and 5N hydrochloric acid (1.72 mL, 8.61 mmol) in tetrahydrofuran (20 mL). The reaction mixture was stirred at 0° C. for 1 h. The solvent was removed in vacuo to give crude ethyl 3-(2-methoxy-3-pyridinyl)alaninate as a white tar, which was used without purification.
