Into a 250-mL sealed bottle, was placed a solution of tert-butyl 3-(2-(2-(2-(tosyloxy)ethoxy)ethoxy)ethoxy)propanoate (14 g, 32.41 mmol, 1.00 equiv) in tetrahydrofuran (5 mL), and CH3NH2 (66.9 g, 712.16 mmol, 21.98 equiv, 33% in ethanol). The resulting solution was stirred overnight at 50° C. The resulting mixture was concentrated under vacuum. The residue was dissolved in 150 mL of dichloromethane. The resulting mixture was washed with 2×150 mL of water and 1×150 mL of brine, dried over sodium sulfate, and concentrated under vacuum. This resulted in 8.2 g (87%) of product as a yellow oil.
