Reaction Conditions

Reaction Steps

A solution of Example 133B (0.060 g, 0.17 mmol), triethylamine (0.070 mL, 0.50 mmol), and butylamine (0.088 mL, 0.85 mmol) in anhydrous acetonitrile (0.6 mL) was heated to 200° C. for 20 minutes in a microwave reactor and concentrated. The concentrate was dissolved in 9:1 methanol/water (1 mL), treated with LiOH (25 mg, 0.6 mmol), and heated to 65° C. for 16 hours. The reaction mixture was concentrated and the concentrate was purified by C18 reverse-phase HPLC using acetonitrile/water/0.1% TFA to provide the desired product.
