Reaction Steps

DIEA (0.03 mL, 0.19 mmol) and methanesulfonyl chloride (0.01 mL, 0.09 mmol) were added to a solution of 273 (27 mg, 0.06 mmol) in CH2Cl2 and stirred for 2 h at room temperature. 2-(Ethylamino)ethanol (17 mg, 0.19 mmol) was added, and the reaction mixture was stirred for 1 h. The crude product was purified directly via HP-LC to provide 274 (6 mg, 16% yield) as a solid. LC-MS (M+H=508, obsd.=508).
