Reaction Steps

To a 500 mL round-bottomed flask were added a stirbar, (S)-2-aminopropan-1-ol (2.151 g, 28.65 mmol), dry DCM (100 mL), and DIPEA (14.0 mL, 81.2 mmol). The mixture was then treated with 2-bromobenzene-1-sulfonyl chloride (6.981 g, 27.32 mmol) and stirred for 66.5 hours before concentrating to dryness and subjecting the residue to FCC to give the title compound. (7.31 g, 91%).
