tert-butyl 2-(2,2,2-trifluoroethylamino)acetate

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

Procedure: The mixture of 2-amino-5-(4-chloromethyl-2-methoxybenzyl)-6-methylpyrimidin-4-yl 2,4,6-triisopropylbenzenesulfonate (6.0 g), tert-butyl 2-(2,2,2-trifluoroethylamino)acetate (2.7 g), sodium carbonate (3.4 g) and potassium iodide (0.5 g) in acetonitrile (48 g) was refluxed for 8 h. After cooling to RT, water (30 g) was added to the mixture and extracted with toluene (48 g). The organic layer was washed with water (30 g) and concentrated in vacuo. The residue was precipitated with n-heptane (18 g) to afford the sub-title compound (12.2 g). was refluxed for 8 h extracted with toluene (48 g) The organic layer was washed with water (30 g) concentrated in vacuo The residue was precipitated with n-heptane (18 g)

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

Procedure: The subtitled compound was synthesized by the method of example 15 step (i) from tert-butyl bromoacetate (13.6 g) and 2,2,2-trifluoroethylamine (8.9 g). The sub-title compound (11 g) was obtained as a colourless oil; 1H NMR (300 MHz, CDCl3); 3.39 (2H, s), 3.20 (2H, q, J=9.4 Hz), 1.44 (9H, s).
