A mixture comprising of 3,5-dichlorobenzyl 2-(2-((tert-butoxycarbonyl)amino)ethyl)morpholine-4-carboxylate (Example 11, step 1) (1 g, 2.308 mmol) and sodium hydride (60% in oil) (0.111 g, 2.77 mmol) in DMF (20 mL) was stirred at 0° C. for 15 minutes. Iodomethane (0.216 mL, 3.46 mmol) was added and the mixture was left to stir at room temperature for 16 hours. The reaction was quenched with water (10 ml) to form a suspension. The suspension was diluted with H2O (100 ml) and extracted with EtOAc (200 ml). The organic portion was separated and washed with H2O (100 ml), dried over MgSO4, filtered and concentrated under reduced pressure to afford the title compound;
