Reaction Steps

Hydrochloric acid (4.0 M in dioxane; 10 mL, 40.1 mmol) was added to a solution of tert-butyl [(6S,9R)-6-(2,3-difluorophenyl)-3-(2,2,2-trifluoroethyl)-6,7,8,9-tetrahydro-5H-[1,2,4]triazolo[4,3-a]azepin-9-yl]carbamate (618 mg, 1.384 mmol, described in Intermediate 13) in 1,4-dioxane (5 mL). After 1 h, the reaction was concentrated in vacuo to give the title compound as a bis hydrochloride salt. MS: m/z=347 (M+1).
