Participants

Reaction Steps

To a mixture of methyl 6-butoxy-2-(dipropylamino)-2,3-dihydro-1H-indene-5-carboxylate (75, 0.35 g, 1 mmol) and N-methylformamide (0.59 g, 10 mmol) in DMF (10 mL) at 100° C. and 25% was added sodium methoxide in methanol (0.22 mL, 1 mmol) dropwise over a period of 10 min. The resulting mixture is cooled to room temperature and quenched with water (100 mL). The resulting solid was purified by chromatography to give an oil that was converted into the HCl salt and crystallized from EtOAc/MeOH to yield the title compound 82 as a white solid (m.p.129-130° C.).
