Reaction Steps

2.5 g (7.75 mmol) 10-Chloro-5,6,8,9-tetrahydro-1,4,7,10a-tetraaza-cyclohepta[f]indene-7-carboxylic acid tert-butyl ester, 1.1 g (9.1 mmol) azetidin-3-yl-acetic acid and 3 mL (17.4 mmol) DIPEA were suspended in 18 mL ethanol. The reaction mixture was stirred at 75° C. over night. The solvent was evaporated and the residue was taken up in EtOAc and water and was acidified using a KHSO4 solution. The organic layer was dried (Na2SO4) and concentrated. The residue was purified by prep. HPLC to yield the corresponding acid (72% of theory).
