Reaction Steps

A solution of (2R)-1-[3,5-bis(trifluoromethyl)benzoyl]-4-[(2E)-3-[(3R)-4-(tert-butoxycarbonyl)morpholin-3-yl]-2-propenyl]-2-(3,4-dimethylbenzyl)piperazine (1.36 g) in ethyl acetate (13 ml) was treated 4N hydrogen chloride in ethyl acetate (3.12 ml) at room temperature for 18 hours and then at 40° C. for 5 hours. The solution was diluted with hexane and stirred for 1 hour. The resulting precipitate was collected by filtration and dried under reduced pressure to give (2R)-1-[3,5-bis(trifluoromethyl)benzoyl]-2-(3,4-dimethylbenzyl)-4-[(2E)-3-[(3R)-3-morpholinyl]-2-propenyl]piperazine dihydrochloride (1.11 g) as a white powder.
