Procedure

To a 20 mL vial which contained a solution of the product from step 1 (40 mg, 0.1 mmol) in HCl (4 N in dioxane 2 mL) was added water (0.3 mL) at 0° C. The mixture was allowed to warm to rt and stir at rt for 24 h. The solvent was removed to yield the crude, which was purified by recrystallization from THF-ether to afford the title product (25 mg, 75%); LCMS; 94%, ESI−, Calcd: 421.5. Found m/z: 420.6 (M-1). 1H NMR (400 MHz, DMSO-d6); δ 1.74-2.09 (m, 5H), 2.16-2.25 (m, 1H), 2.31-2.40 (m, 2H), 3.03 (br, 2H), 3.45-3.80 (m, 3H), 4.16-4.20 (m, 1H), 4.20-4.23 (m, 1H), 6.52 (t, J=2.0 Hz, 1H), 6.87 (s, 1H), 7.04-7.06 (m, 5H), 7.71 (d, J=1.6 Hz, 1H), 7.80 (d, J=9.2 Hz, 2H), 8.42 (d, J=2.4 Hz, 1H):
