Procedure

4-Bromobutyryl chloride (29.4 mg, 0.158 mmol) was added to a solution of 8-(aminomethyl)-10-(5-chlorofuran-2-yl)-1,3-dimethyl-5-(4-methylthiazol-2-yl)-7,8-dihydro-1H-pyrimido[4′,5′:3,4]pyrrolo[2,1-c][1,4]oxazine-2,4(3H,10H)-dione (61 mg, 0.132 mmol) and triethylamine (0.022 mL, 0.158 mmol) in DCM (4 mL). The mixture was stirred at room temperature for 3.5 hours, then diluted with DCM (30 ml) and washed with saturated NaHCO3(aq) (30 ml). The organic phase was passed through a hydrophobic frit and evaporated under vacuum to afford the title compound as a crude material which was used directly

Workup

  1. washwashed with saturated NaHCO3(aq) (30 ml)
  2. customevaporated under vacuum
