Procedure: Heated a mixture tert-butyl 4-(3-bromo-2-oxopropyl)piperidine-1-carboxylate (1.38 g, 4.32 mmol), 1-(5-bromo-3-phenoxypyridin-2-yl)thiourea (1.0 g, 3.08 mmol), triethylamine (0.731 mL, 5.24 mmol), and ethanol (50 mL) at reflux overnight. Cooled to ambient temperature and partitioned between into water and ethyl acetate. Washed the organic layer with water, brine, dried and concentrated. Purified by MPLC (Biotage) eluting with 3:1 hexane:ethyl acetate to afford the title compound (1.54 g, 92%) as a white powder: 1H NMR (CDCl3) δ 8.66 (s, 1H), 8.13 (s, 1H), 7.43 (t, 2H), 7.25 (t, 1H), 7.12 (s, 1H), 7.06 (d, 2H), 6.45 (s, 1H), 4.08 (m, 2H), 2.67 (m, 2H), 2.56 (d, 2H), 1.85 (m, 1H), 1.66 (m, 2H), 1.44 (s, 9H), 1.15 (m, 2H). at reflux overnight partitioned between into water and ethyl acetate Washed the organic layer with water, brine dried concentrated Purified by MPLC (Biotage) eluting with 3:1 hexane

Procedure: To a solution of tert-butyl 4-(2-(trimethylsilyloxy)allyl)piperidine-1-carboxylate (6.43 g, 20.5 mmol) in THF (100 mL) at 0° C. was added sodium bicarbonate (2.58 g, 30.7 mmol) followed by 1-bromopyrrolidine-2,5-dione (3.65 g, 20.5 mmol). Warmed to ambient temperature and stirred 90 minutes. Partitioned between ether (150 mL) and saturated sodium bicarbonate. The aqueous layer was reextracted with ether (100 mL). The combined organic layers were washed with saturated bicarbonate, brine, dried, and concentrated to afford the title compound (7.2 g, 110% yield) as a yellow oil. Purity was 85% with the major impurity being succinimide. The crude material was used in the next step. Partitioned between ether (150 mL) and saturated sodium bicarbonate The combined organic layers were washed with saturated bicarbonate, brine dried concentrated
