Hydrochloric Acid → 3-[(Pyridin-3-ylmethyl)-amino]-phthalic acid

Participants

Reaction Steps

3-[(Pyridin-3-ylmethyl)-amino]-phthalic acid dimethyl ester (0.91 g, 3.03 mmol) was treated in the same manner as described above for the synthesis of 3-(2-methoxy-ethylamino)-phthalic acid except the pH of crude reaction mixture was adjusted to 2–3 by dropwise addition of concentrated HCl. The solvent was then evaporated in vacuo leaving a dry salt mixture that was used without further purification.
