Reaction Steps

N-[(1S,2R)-2-amino-1-benzyl-3-fluoropropyl]-2-[(isopropylsulfonyl)(methyl)amino]-6-((2-methoxyethyl){[(1S,2S)-2-methylcyclopropyl]methyl}amino)isonicotinamide was prepared via procedure described in Example 95. A solution of N-[(1S,2R)-2-amino-1-benzyl-3-fluoropropyl]-2-[(isopropylsulfonyl)(methyl)amino]-6-((2-methoxyethyl){[(1S,2S)-2-methylcyclopropyl]methyl}amino)isonicotinamide trifluoroacetate (0.11 g, 0.2 mmol) in 5 mL methylene chloride was treated with NCS (0.026 g, 0.2 mmol) and the resulting mixture was stirred at ambient temperature for 24 hours. The reaction was evaporated in vacuo and purified by reverse phase LC to generate N-[(1S,2R)-2-amino-1-benzyl-3-fluoropropyl]-3-chloro-2-[(isopropylsulfonyl)(methyl)amino]-6-((2-methoxyethyl){[(1S,2S)-2-methylcyclopropyl]methyl}amino)isonicotinamide trifluoroacetate as a yellow solid: 1H NMR (CDCl3) δ 7.25 (m, 5H), 6.21 (s, 1H), 4.65 (m, 4H), 3.85 (m, 1H), 3.60 (m, 3H), 3.40 (m, 3H), 3.31 (s, 3H), 3.22 (s, 3H), 3.18 (m, 2H), 1.42 (m, 6H), 1.01 (d, J=5.8 Hz, 3H), 0.64 (m, 2H), 0.36 (m, 1H), 0.25 (m, 1H). ES MS (M+H)=598.8.
