Methyl iodide → 2-(1,1-Dioxo-1lambda6-thiomorpholin-4-yl)-7-methyl-4-p-tolyl-6,7,8,9-tetrahydro-5H-pyrimido[4,5-d]azepine

Participants

Reaction Steps

A mixture of 2-(1,1-dioxo-1λ6-thiomorpholin-4-yl)-4-p-tolyl-6,7,8,9-tetrahydro-5H-pyrimido[4,5-d]azepine (0.060 g, 0.00016 mol), iodomethane (0.015 mL, 0.00016 mol) and N-ethyl-N-(1-methylethyl)-2-propanamine (0.056 mL, 0.00032 mol) in DCM (2 mL) was stirred at rt for 3 h. The mixture was diluted with DCM and washed with water (3×) and satd. aq. NaCl. The separated organic layer was dried and concentrated. The residue was purified by FCC [7 N NH3/MeOH)/DCM] to give 0.010 g (16%) of the title compound.
