Participants

Reaction Steps

To a solution of methyl 2-(dipropylamino)-2,3-dihydro-6-(phenylmethoxy)-1H-indene-5-carboxylate (74, 0.95 g, 2.5 mmol) and formamide (1.1 g, 25 mmol) in DMF (10 mL) at 100° C. was added 25% sodium methoxide in methanol (2.5 mmol, 0.57 mL) dropwise. The mixture stirred for 2 h. The reaction was cooled to rt and quenched with water (100 mL). The resulting precipitate was stirred for 0.5 h and the solvent was removed via filtration. This solid was crystallized from EtOAc/MeOH to give a white solid that was converted into the HCl salt and crystallized from EtOAc/MeOH to give the title compound 78 as a white solid (m.p. 247-248° C.).
