benzyl 3,3,3-trifluoro-2-hydroxy-2-methylpropanoate

Conditions: temp:0.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A cooled (0° C.) solution of benzyl 3,3,3-trifluoro-2-hydroxy-2-methylpropanoate (Int. D1) (100 mg, 0.403 mmol) in DMF (4 ml) was treated with sodium hydride (16.11 mg, 0.403 mmol) followed by benzyl bromide (0.048 ml, 0.403 mmol) and stirred at 0° C. for 2 h. The reaction mixture was allowed to warm to room temperature and stirring continued for a further 3 hrs. The reaction mixture was partitioned between EtOAc and 0.1M HCl solution. The organic phase was washed with saturated brine, dried over magnesium sulfate and concentrated in vacuo to afford the title compound as an oil. to warm to room temperature stirring continued for a further 3 hrs The reaction mixture was partitioned between EtOAc and 0.1M HCl solution The organic phase was washed with saturated brine dried over magnesium sulfate concentrated in vacuo

Conditions: temp:0.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 3,3,3-Trifluoro-2-hydroxy-2-methylpropanoic acid (0.6 g, 3.80 mmol) was dissolved in MeCN (5 ml). DIPEA (0.663 ml, 3.80 mmol) was added and stirred for 5 min. Benzyl bromide (541 mg, 3.16 mmol) was added and the reaction mixture was stirred at RT for 16 h followed by 70° C. for 16 h. After cooling to RT, the solvent was removed in vacuo and the resulting residue was dissolved in DCM. The mixture was washed with water and the organic portion was separated by means of a phase separator. The solvent was removed in vacuo to afford the title compound. the reaction mixture was stirred at RT for 16 h followed by 70° C. for 16 h the solvent was removed in vacuo the resulting residue was dissolved in DCM The mixture was washed with water the organic portion was separated by means of a phase separator The solvent was removed in vacuo
