To the suspension of compound Intermediate 233 (138 mg, 0.5 mmol, 1.0 equiv), tetrazolo[1,5-a]pyrimidine (Intermediate 234) (67 mg, 0.55 mmol, 1.1 equiv.) and Hunig's base (0.3 mL, 1.75 mmol, 3.5 equiv.), (CuOTf)2.Benzene (150 mg, 0.6 mmol, 1.2 equiv.) was added at room temperature in one portion under N2. After 6 hours at room temperature, HPLC analysis indicated the complete consumption of Intermediate 233. Allyl bromide (242 mg, 2.0 mmol, 4.0 equiv.) was added and the reaction solution was stirred for another 2 hours. The same workup/purification procedure were followed to afford Intermediate 235 (113 mg, 0.26 mml, 52% yield) along with Intermediate 236 (49 mg, 0.12 mmol, 25% yield).
