Butyl Chloride → HCID 13103326, compound

Participants

Reaction Steps

To a suspension of 1.2 g of 2-amino-4,6-dimethylpyrimidine in 25 ml of acetonitrile was added 2.6 g of 1,1'-biphenyl-2-sulfonyl isocyanate with stirring at ambient temperature. After stirring for 2 hours, the mixture was filtered and the filtrate concentrated in vacuum. The residue thus obtained, after trituration with chlorobutane, melted at 78° with gas evolution. It showed peaks in the nuclear magnetic resonance spectrum (60 MHz) at δ 2.2, (singlet, CH3); δ 6.56, (singlet, CH of pyrimidine) and at δ 6.8-7.9, (multiplet, phenyl hydrogens) in a ratio of 6:1:9, consistent with the desired structure.
