Participants

Reaction Steps

To a solution of 70 (1.71 g, 5.38 mmol) in THF (20 mL) was added 1-Boc-4-aminothiocarbonyl piperidine (1.31 g, 5.36 mmol) and the solution was allowed to stir at r.t. for 3 h. The reaction mixture was then poured onto saturated aqueous NaHCO3 (50 mL) and extracted with AcOEt (2×50 mL). The combined organic portions were then evaporated to afford 71 (2.58 g, 5.41 mmol, 100%) as a white powder. 1H NMR (400 MHz, CDCl3) δ 1.43 (s, 9H), 1.64-1.84 (m, 4H), 2.07-2.17 (m, 2H), 2.81-2.94 (m, 2H), 3.13-3.24 (m, 1H), 7.17 (s, 1H), 7.74 (d, J=2.4 Hz, 1H), 8.32 (d, J=2.1 Hz, 1H), 8.48 (d, J=2.1 Hz, 1H), 8.97 (br s, 1H).
