Reaction Steps

A suspension of 1-(bromomethyl)-4-nitro-benzene (250 mg, 1.157 mmol) in dichloromethane (5 mL) was treated with triethylamine (200 μL, 1.39 mmol) and morpholine (110 μL, 1.27 mmol) then stirred at room temperature for 1.5 hrs. The solution was diluted with dichloromethane (20 mL) then washed with water (2×20 mL). The organic extract was dried (MgSO4), filtered and concentrated to give (i) which was used in subsequent reactions without further purification. 1H NMR (400 MHz, CDCl3) δ 8.21-8.16 (m, 2H), 7.56-7.50 (m, 2H), 3.76-3.69 (m, 4H), 3.59 (s, 2H), 2.49-2.42 (m, 4H).
