A solution of tert-butyl (2-amino-4-(thiophen-2-yl)phenyl)carbamate (1.2 g, 4.13 mmol, 1.0 eq.), tetrahydro-2H-pyran-4-carboxylic acid (0.65 g, 4.96 mmol, 1.2 eq.), HATU (3.14 g, 8.27 mmol, 2.0 eq.) and Hünigs base (1.80 mL, 10.33 mmol, 2.5 eq.) in DMF (15 mL) was stirred for 18 h at room temperature. The reaction mixture was diluted with water. The solid was isolated by filtration and washed with hexanes to afford tert-butyl (2-(tetrahydro-2H-pyran-4-carboxamido)-4-(thiophen-2-yl)phenyl)carbamate (1.3 g, 78% yield).
