Reaction Steps

A mixture of 5-chloro-2-nitrophenylamine (1.3 g, 7.0 mmol), 4-hydroxypiperidine (2.2 g, 20 mmol), and K2CO3 (1.0 g, 7 mmol) in DMF (20 mL) was stirred at 120° C. for 18 h. The reaction mixture was cooled to room temperature, poured into water (50 mL) and extracted with EtOAc (3×50 mL). The combined organic extracts were dried over sodium sulfate, concentrated in vacuo, and the oily residue was triturated with 70/30 EtOAc/CHCl3 (8 mL) to yield a yellow solid. The solid product was collected by filtration, washed with 70:30 EtOAc/CHCl3 (8 mL), and dried in vacuo (0.63 g, 38%).
