Reaction Steps

The product of step D (207 mg, 0.488 mmol) was dissolved in dichloromethane (1.63 mL) and trifluoroacetic acid (1.62 mL, 21.0 mmol) was added. At 1.75 h the volatiles were removed to yield an oil, which was dissolved in 1 mL of MeOH and 1.5 mL of 7 M NH3 in MeOH. After 30 min all volatiles were removed. The free base was used without further purification. 1H NMR (500 MHz, CDCl3) δ 9.10 (d, 1H), 8.26 (dd, 1H), 7.68 (d, 1H), 4.78 (d, 1H), 4.71 (d, 1H), 3.89-3.84 (m, 1H), 3.53-3.49 (m, 1H), 3.46-3.41 (m, 1H), 3.15 (s, 3H), 2.93-2.81 (m, 2H), 2.19-2.12 (m, 1H), 2.02-1.94 (m, 1H), 1.80-1.68 (m, 2H), 1.80-1.68 (m, 2H), 1.38-1.30 (m, 1H), 1.19-1.09 (m, 1H), 0.89-0.22 (m, 2H), 0.11-0.06 (m, 1H).
