(R)-9-[2-(Hydroxypropyl] Adenine (Desphosphoryl Tenofovir) (cas# 14047-28-0) is a useful reagent for preparing the antiviral drug tenofovir. | [Synthesis]
To a reaction flask was added 200 mL of N,N-dimethylformamide (DMF) protected by N2, adenine (30.0 g, 0.222 mol, 1 equiv) and stirred. NaOH (0.45 g, 0.011 mol) and R-propylene carbonate (28.5 g, 0.279 mol, 1.26 eq.) were subsequently added. The reaction mixture was warmed to 130-140 °C within 12 h of the sampling test, and the reaction was stopped when the adenine content dropped to 1% or less. Slowly cooled to below 90°C, 200 mL of toluene was added, cooling was continued to 0-5°C, and the mixture was stirred for 2 hours. Filtered and dried to give 38.13 g white solid in 87% yield. | [References]
