Procedure

Preparation C7, Step 4: 6-tert-Butyl-pyrrolo[2,1-f][1,2,4]triazin-4-ol (0.43 mg, 2.26 mmol, 1 eq.) and POCl3 (4.21 mL, 45.2 mmol, 20 eq.) were mixed and refluxed for 4 hours. The mixture was stripped then restripped 3× from methylene chloride and then dissolved in methylene chloride and rinsed 3× with sat'd NaHCO3, 1× with brine. The organic layers were collected, dried and stripped in vacuo to yield 490 mg of 6-tert-butyl-4-chloro-pyrrolo[2,1-f][1,2,4]triazine as an amber oil. LCMS detects (M+H)+=210.
