Methanaminium, N-((dimethylamino)(3H-1,2,3-triazolo(4,5-b)pyridin-3-yloxy)methylene)-N-methyl-, hexafluorophosphate(1-) (1:1) → HCID 86636284, compound

Participants

Reaction Steps

A solution of {1-[(5-methylisoxazol-3-yl)carbonyl]piperidin-4-yl}acetic acid (16 mg, 0.063 mmol) (prepared in Example C49, step I), N,N,N′,N′-tetramethyl-O-(7-azabenzotriazol-1-yl)uronium hexafluorophosphate (65 mg, 0.17 mmol) in N,N-dimethylformamide (0.8 mL) and N,N-diisopropylethylamine (26 μL) was stirred for 15 minutes. A solution of 6-fluoro-2,4,8,22-tetraazatetracyclo[14.3.1.1(3,7).1(9,13)]docosa-1(20),3(22),4,6,9(21),10,12,16,18-nonaen-12-amine bis(trifluoroacetate) (20 mg, 0.06 mmol) in N,N-dimethylformamide (0.3 mL) and was added to the previous solution and stirred overnight. The reaction mixture was purified by preparative HPLC (pH 2) to give the desired product (4 mg, 12%). LCMS for C30H31FN7O3 (M+H)+: m/z=556.2
