Pyrrolidine (1.82 g, 25 mmol), K2CO3 (3.0 g, 1.04 eq.), 3-bromo-2,2-dimethyl-propan-1-ol (8.45 g, 50 mmol, 2 eq.) were heated together at 90° C. overnight. The reaction was allowed to cool to room temperature and quenched with 2M HCl solution (50 ml) and extracted with TBME (3×50 ml). The aqueous phase was basified to pH 14 with 2M NaOH solution and extracted with DCM (3×50 ml). The combined organic extracts were dried over MgSO4, filtered, washed with DCM and concentrated in vacuo to give the title compound (1.03 g, 26%) as a pale yellow oil.
