Reaction Steps

A solution of (S)-benzyl(1-hydroxypropan-2-yl)carbamate (400 g, 1.91 mol) and triethylamine (270 g, 2.67 mol) in methylene chloride (2.4 L) was cooled to 0° C. To this mixture was added methanesulfonyl chloride (263 g, 2.30 mol) at an internal temperature of 5° C. or below. Subsequently, the resulting reaction mixture was stirred at room temperature for 16 hours. After confirming the disappearance of the starting materials by TLC, to the reaction mixture was added purified water. The resulting organic layer was partitioned, washed with saturated brine, dried over magnesium sulfate, and filtered. The filtrate was concentrated under reduced pressure to give the target product as a yellow solid (519 g, yield 94.5%).
