Procedure
To a solution of #170 (18.2 mg, 0.076 mmol, 1 eq.) in dichloromethane (1.8 mL) and N,N-dimethylformamide (0.3 mL) was added N,N-diisopropylethylamine (0.040 mL, 0.228 mmol, 3 eq.) followed by HATU (29.2 mg, 0.076 mmol, 1 eq.). After stirring for 10 minutes at room temperature, #176 (45 mg, 0.076 mmol, 1 eq.) was added. The reaction was stirred at room temperature for 18 hours and additional HATU (29 mg, 0.076 mmol, 1 eq.) was added. After 8 hours the reaction was concentrated in vacuo to provide #183 (61.0 mg, quantitative) which was taken into the next step without further purification. LC-MS (Protocol Q1): m/z 826.6 [M+Na+], retention time=1.05 minutes.
