実験手順

A solution of sodium bicarbonate (0.78 g) in water (30 ml) was added to the product of step (g) (2.8 g). The resulting solution was filtered then evaporated to small volume and diluted with acetone. Crystallisation occurred and the resulting crystals were filtered off and recovered as an off-white solid, which was the desired sodium salt (2.65 g).
