Reaction Steps
A solution of 4-(2-propyl)oxyindan-2,2-dicarboxylic acid (11.5 g) in NMP (20 ml) was heated to 150° C. After a further 15 minutes, the solution was allowed to cool to room temperature, and was poured into aqueous hydrochloric acid (1500 ml, 1 M). This mixture was extracted with ethyl acetate (2×500 ml) and a standard workup gave 4-(2-propyl)oxyindan-2-carboxylic acid (3.98 g) as a dark brown solid, which was used without further purification.
