Chlorotrimethylsilane → 2-Methyl-N,N-bis(trimethylsilyl)pyrimidin-4-amine

Participants

Reaction Steps

A slurry of 4-amino-2-methylpyrimidine (2.04 g, 18.69 mmol) in 1,1,1,3,3,3-hexamethyldisilazane (40 mL) and chlorotrimethylsilane (0.36 mL, 2.8 mmol) was heated at 150° C. for 8 h. At this time, the reaction mixture was close to a homogeneous solution. The resulting slightly orange solution was then filtered to remove any remaining solids. The filtrate was concentrated in vacuo to afford 4-(1,1,1,3,3,3-hexamethyl-disilazan-2-yl)-2-methyl-pyrimidine as an off-white solid (2.18 g).
