Triethylamine → HCID 86611173, compound

Participants

Reaction Steps

Methylene chloride (400 mL) and triethylamine (83.9 mL, 0.60 mol) were added to the flask containing (R)-2-boc-amino-propan-1-ol (from step 1). The reaction mixture was cooled in an ice bath for 30 minutes, and then methanesulfonyl chloride (37.0 mL, 0.478 mol) was added dropwise over a five minute period. The reaction mixture was stirred for one hour, then the ice bath was removed and the reaction mixture was stirred for 18 hours at room temperature. The reaction mixture was washed with 10% aqueous NaOH solution, and the organic layer was dried over MgSO4, filtered, and concentrated under reduced pressure to give 91.93 g of (R)-2-boc-amino-1-methanesulfonyl-propan-1-ol.
