Participants

Reaction Steps

A solution of (RS) 3-(6-amino-pyrid-3-yl)-butanoic acid hydrochloride (12.0 g, Reference Example 20) in methanol (300 mL) was treated with concentrated sulphuric acid (3.0 mL) then heated at reflux temperature for 8 hours. The reaction mixture was concentrated, then basefied with 5% aqueous sodium bicarbonate and then extracted with ethyl acetate .
