Procedure

Pyrrolo[1,2-c]pyrimidine-3-carboxylic acid hydrochloride (0.33 g, 1.66 mmol) and TEA (2.0 mL, 14.35 mmol) are dissolved in 15 mL THF. Diphenylphosphinic chloride (0.47 g, 1.99 mmol) is added dropwise. After 1 h, (R)-(+)-3-aminoquinuclidine dihydrochloride is added and the reaction is allowed to stir at RT. After 1 day, 1N NaOH is added and the mixture is extracted with CHCl3. The combined organic layers are dried (MgSO4), filtered and concentrated. The residue is purified by chromatography (Biotage 40S, 90:9:1 CHCl3/MeOH/NH4OH) to afford 0.45 g (100%) of product. The hydrochloride salt is prepared and recrystallized from CH3CN/Et2O.
