More (tetrahydro-2H-pyran-4-yl)methanamine (1 g, 0.7 equiv), Hunig's base (2.2 mL, 1 equiv.) and DMAP (ca. 10 mg) were added and the reaction was heated at 45° C. for 18 h. More Hunig's base (3 mL) and DMAP (80 mg) was added and heating continued at 50° C. for 5 h. The reaction was then concentrated in vacuo to give a residue which was taken up in EtOAc (100 mL) and washed with saturated aqueous ammonium chloride (100 mL) and brine, dried over magnesium sulfate and concentrated in vacuo to give a residue which was purified on an 80 g silica gel column eluted with 0 to 100% EtOAc in hexanes, then filtered and dried in the lyophilizer to give the title compound (0.985 g, 30.5% yield) as a white solid.
