Procedure

To a stirred solution of 3-isoxazolecarboxylic acid (0.02 g, 0.18 mmol), and triethylamine (0.1 mL, 0.72 mmol) in dichloromethane (2 mL) was added HATU (0.07 g, 0.18 mmol). The resulting mixture was stirred 20 minutes. To this mixture was added 38-2 (0.04 g, 0.14 mmol) and the resulting mixture was stirred room temperature overnight. The mixture was washed with water and concentrated. Flash column separation using a 10-70% ethyl acetate/hexane gradient gave 38-3. (0.045 g, 85%). HRMS (M+H)+: observed=386.2188, calculated=386.2187
