Di-tert-butyl dicarbonate → tert-Butyl (6-chloro-2-methylpyrimidin-4-yl)carbamate

Participants

Reaction Steps

To a solution of 6-chloro-2-methylpyrimidin-4-amine (1.0 equiv.) in THF (0.17M) was added BOC2O (1.1 equiv.) and DMAP (cat.). The reaction was allowed to stir overnight, then concentrated to a yellow crude, and filtered through a pad of SiO2 eluting with EtOAc and hexanes (1:1) to afford an off-white solid (78%). LCMS (m/z): 244.1 (MH+); LC Rt=3.69 min.
