2-Methoxypropene → HCID 18341303, compound

Participants

Reaction Steps

To a mixture of 2-bromo-N-(1(S)-hydroxymethyl-2-phenylethyl)acetamide (1.55 g, 5.45 mmol) and p-toluenesulfonic acid monohydrate (100 mg) in CH2Cl2 (50 mL) was added 2-methoxypropene (1.50 mL, 15.7 mmol) dropwise via syringe. After 15 minutes at ambient temperature, the resultant mixture was washed with 1M pH7 phosphate buffer (25 mL) and brine (25 mL), dried over Na2SO4, and concentrated to give a dark solid, which was triturated with MTBE/hex to provide 1.46 g (86%) of 3-(2-bromoacetyl)-2,2-dimethyl-4(S)-phenylmethyl-oxazolidine as a pale yellow solid.
