Procedure

Dissolved the product from Example 39G (285 mg, 0.502 mmol), (S)-1-(tert-butoxycarbonyl)pyrrolidine-2-carboxylic acid (162 mg, 0.753 mmol), HATU (305 mg, 0.803 mmol) and Hunig's base (0.263 mL, 1.506 mmol) in DMSO (5 mL) and stirred at room temperature for 1 h. Dichloromethane (50 mL) was added followed by extraction with water (2×50 mL), the organic extract dried, concentrated and the residue dissolved in methanol (10 mL) followed by the addition of potassium carbonate (400 mg, 2.89 mmol) and stirred the bright yellow solution at room temperature for 30 min. The solution was then filtered and the filtrate concentrated to an oil, which was dissolved in a 95/5 dichloromethane/methanol mixture (50 mL) and extracted with water (20 mL). The organic extract was dried and concentrated to give the title product (350 mg, 91%) as a light yellow solid and a 1/1 mixture of stereoisomers.
