Reaction Steps

Ammonium formate (8.1 g) and palladium (10 wt. % on activated carbon, 4.0 g) were added to a solution of 2-benzyl-5-methoxy-8-methylene-1,2,3,3a,8,8a-hexahydroindeno[1,2-c]pyrrole (8.1 g, 27.8 mmol) in MeOH (140 mL). The reaction mixture was stirred for 4 hours at 60° C. and then filtered through celite. The celite was washed with MeOH (200 mL) and the filtrate was concentrated to afford 5.6 g (quantitative yield) of the title compound. An aliquot of the crude product was purified by reverse-phase liquid chromatography to afford the title compound. MS calculated for C13H17NO+H: 204, observed: 204.
