Reaction Steps

1.2 g (6.6 mmol) methyl 2,3-dihydro-1H-isoindole-5-carboxylate are dissolved in 5 ml formic acid, combined with 2 ml formalin solution (37% solution in water), heated to 70° C. for 3.5 hours and stirred for 16 hours at RT. The reaction mixture is evaporated down i. vac. and combined with 0.1 N sodium hydroxide solution and extracted three times with ethyl acetate. The combined organic phases are dried on sodium sulphate, filtered and evaporated down i. vac.
