The resulting brown solution was stirred overnight. The reaction mixture was partitioned between water (10 mL) and EtOAc (20 mL). The layers were separated and the aqueous layer was back- extracted with EtOAc (20 mL). The combined organic layers were concentrated to yield a dark syrup, which was dissolved in MeOH (3 mL) and treated with concentrated HC1 (3 drops). The mixture was stirred overnight and subsequently purified by preparative HPLC, eluting with 25-50percent ACN in water (containing 0.05percent TFA). The pure fractions were lyophilized to give a TFA salt of the title compound as a light yellow solid (5.3 mg, 14percent). 1H NMR (400 MHz, DMSO-d6) delta ppm 0.82 (s, 4 H), 2.37 (s, 3 H), 3.55 (s, 2 H), 7.14 - 7.18 (m, 2 H), 7.66 (s, 1 H), 7.70 (s, 1 H), 7.68 (s, 1 H), 8.00 - 8.06 (m, 2 H), 8.75 (s, 1 H).

The solution was diluted withiN hydrochloric acid and dichloromethane. The layers were then separated and thelayer was extracted with dichloromethane. The organics were combined, dried over magnesium sulfate, filtered, and the solvent was removed in vacuo. Purification yielded theproduct The title compound was prepared following general procedure B, except(1 -amino cyc lopropyl)methano 1 (as the HC1 salt) was the amine reactant, and the contents were heated to 100 °C for 6.5 h.
