Reaction Steps

tert-Butyl [(1R,3S)-3-isopropyl-3-({4-[4-(trifluoromethyl)pyridin-2-yl]piperazin-1-yl}carbonyl)cyclopentyl]carbamate (150 mg, 0.31 mmol) was treated with a 4.0 M solution of HCl in 1,4-dioxane (10 mL) at room temperature for 1 hr and concentrated at reduced pressure to give the product which was used for next step without purification. MS calculated for C19H27F3N4O: (M+H) 385; found 385.2.
