A mixture of 2-(3-chloropyrazin-2-yl)-2-methylpropanoic acid (2.0 g, 9.97 mmol), tert-butyl 4-amino-1-piperidinecarboxylate (2.396 g, 11.96 mmol), DIEA (2.61 ml, 14.95 mmol), and hatu (4.17 g, 10.97 mmol) in DMF (30 mL) was stirred at RT overnight. The reaction mixture was then heated to 55° C. for 4 h, cooled, and H2O was added, the light brown solid was collected, dried and used in the next step (3.1 g, 81%). MS (M+1): 383.1
