A solution of 2-({[tert-butyl(dimethyl)silyl]oxy}methyl)morpholine (2.1 g, 9.07 mmol) in DCM (20 mL) was treated with triethylamine (3.8 mL, 27.2 mmol) and 1-chloro-3-iodopropane (1.95 mL, 18.1 mmol). The reaction mixture was stirred at rt overnight. The reaction mixture was concentrated under reduced pressure then purified by MPLC (ISCO, 0% MeOH/100% DCM to 25% MeOH/75% DCM). The product was isolated as an oil (560 mg, 20%): HPLC MS RT=2.66 min, MH+=308.4, 310.4; 1H NMR (DMSO-d6) δ: 3.79-3.69 (1H, m), 3.63 (2H, t) 3.59-3.52 (1H, m), 3.50-3.36 (3H, m), 2.73 (1H, d), 2.61 (1H, d), 2.35 (2H, t), 1.94 (1H, td), 1.83 (2H, qt), 1.73 (1H, t), 0.83 (9H, s), 0.00 (6H, s).
