Triethylamine → [2-Amino-6-(1-ethanesulfonyl-piperidin-4-ylamino)-pyridin-3-yl]-(2-fluoro-phenyl)-methanone

Participants

Reaction Steps

To a solution of [2-Amino-6-(piperidin-4-ylamino)-pyridin-3-yl]-(2-fluoro-phenyl)-methanone (19.2 mg, 0.0611 mmol, Example 9) in methylene chloride (1.5 mL) were added triethylamine (12.6 mg, 0.124 mmol, Aldrich) in methylene chloride (0.2 mL) and a solution of ethanesulfonyl chloride (8.66 mg, 0.066 mmol, Aldrich 99+%) in methylene chloride (0.2 mL) at room temperature. After ˜30 mins the reaction mixture was concentrated and purified by reversed phase HPLC as described in Example 11 to give [2-Amino-6-(1-ethanesulfonyl-piperidin-4-ylamino)-pyridin-3-yl]-(2-fluoro-phenyl)-methanone as a white solid (15.1 mg, 60 % yield). HRMS, observed: 407.1533, calcd for (M+H)+: 407.1548.
