Procedure
A solution of 2-(trifluoromethyl)pyrrolidine (500 mg, 3.59 mmol) in DCM (10 ml) was treated with chloroacetyl chloride (0.31 ml, 3.77 mmol) and stirred at RT for 1 h. The resulting mixture was concentrated in vacuo to afford the title compound as a yellow oil which was used without further purification; 1H NMR (400 MHz, CDCl3) δ 4.84 (1H, m), 4.11 (2H, s), 3.71 (2H, m), 2.23 (2H, m), 2.07 (2H, m).
