Reaction Steps
A mixture of the product from step 3, methanesulfonamide (32 mg), HBTU (86 mg), and DIPEA (0.18 mL) in dichloromethane (1.7 mL) was stirred at rt for 16 hr. Diluted with EtOAc, the contents were washed with 1:4 mixture of 1M HCl and 1M NaH2PO4 (2×) and brine, and dried (Na2SO4). The crude was purified with HPLC. LCMS (Method D): RT=5.35 min, m/z: 400.1 [M+H]+. 1H NMR (400 MHz, DMSO-d6) δ 12.08 (s, 1H), 7.78 (d, J=7.7 Hz, 1H), 7.14 (d, J=12.3 Hz, 1H), 4.13-3.98 (m, 2H), 3.13 (s, 3H), 2.18 (s, 1H), 2.04 (s, 2H), 1.90-1.56 (m, 4H), 1.55-1.39 (m, 1H), 1.19 (m, 1H).
