4-Methylmorpholine → Prop-1-en-2-yl 6-(4-nitronaphthalen-1-yloxy)pyrimidin-4-ylcarbamate

Participants

Reaction Steps

To a solution of 6-(4-nitronaphthalen-1-yloxy)pyrimidin-4-amine (89 mg, 0.315 mmol) and NMM (45 μl, 0.410 mmol) in THF (2.0 mL) at 0° C. was added, dropwise, a solution of prop-1-en-2-yl carbonochloridate (45 μl, 0.410 mmol) in THF (1.0 mL) and the reaction mixture warmed to RT for 15 hr and then partitioned between EtOAc (20 mL) and water (5.0 mL). The aq layer was separated and extracted with EtOAc and the combined organic layers were dried (MgSO4) and then evaporated in vacuo to afford the title compound as a yellow oil (109 mg, 87%); Rt 2.54 min (Method 2); m/z 367 (M+H)+ (ES+). This material was used directly in the next step (below) without further purification.
