Triethylamine → HCID 11262631, compound

Participants

Reaction Steps

The product from Example 169A (13.2 mg, 0.06 mmol) was dissolved in N,N-dimethylformamide (0.25 mL) and N-hydroxybenzotriazole (13 mg, 0.10 mmol) and 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide (18.4 mg, 0.10 mmol) were added followed by the product from Example 2C (34.2 mg, 0.06 mmol). Triethylamine (9 uL, 0.06 mmol) was added and the mixture was stirred at ambient temperature for 18 hours. The solution was concentrated and the crude residue was purified on a 2 mm preparative silica gel TLC plate (5% CH3OH/CHCl3) to give an amorphous solid (38.4 mg, 83%). 1H NMR (CDCl1) δ 8.65 (d, 1H), 7.86 (d, 2H), 7.78-7.60 (m, 2H), 7.27-7.11 (m, 9H), 6.94-6.70 (br s, 1H), 6.36-6.24 (br s, 1H), 6.24-6.04 (br d, 1H), 6.02-5.84 (br d, 1H), 5.41-5.25 (m, 2H), 4.23-4.10 (m, 1H), 4.10-3.95 (q, 1H), 3.75 (d, 1H), 3.67 (s, 3H), 3.66 (s, 3H), 3.63 (s, 3H), 2.98-2.8 (m, 3H), 2.8-2.65 (m, 1H), 0.91 (s, 9H).
