Participants

Reaction Steps

To a solution of 3-[4-((R)-3-morpholin-4-yl-1-phenylsulfanylmethyl-propylamino)-3-trifluoromethanesulfonyl-benzenesulfonylamino]-5,6-dihydro-8H-[1,2,4]triazolo[4,3-a]pyrazine-7-carboxylic acid tert-butyl ester (130 mg, 0.168 mmol) in dichloromethane (3 mL) under nitrogen was added trifluoroacetic acid (0.323 mL, 4.19 mmol), and the reaction was stirred for 2.5 hours. The reaction mixture was then concentrated and diluted with water and CH2Cl2. It was then basified to pH approximately 8 with saturated Na2CO3. The organics were extracted three times with CH2Cl2. The combined organic layers were washed with brine, dried over Na2SO4, filtered and concentrated under reduced pressure to afford the title compound (112 mg, 99% yield). MS [m/z; (M+1)+]: 676.5
