Participants

Reaction Steps

To a solution of EXAMPLE 12 (26 mg) and triethylamine (25 μL) in 1 mL dioxane was added methanesulfonyl chloride (5.53 μL). The mixture was stirred for 24 hours and concentrated. The title compound was purified by RP-HPLC using a gradient elution of 10/90 to 70/30 acetonitrile/0.1% TFA in water at 254 nm over 30 minutes. The free base was isolated after eluting from an ion exchange column (10 g). 1H NMR (500 MHz, DMSO-d6) δ 11.28 (s, 1H), 8.14 (m, 1H), 7.95 (s, 1H), 7.29 (s, 2H), 7.03 (m, 1H), 6.70 (m, 1H), 4.41 (s, 2H), 2.96 (s, 3H), 2.46 (m, 1H), 0.68 (d, 4H).
