YieldReaction ConditionsOperation in experiment
20% In N,N-dimethyl-formamide; for 11h;Inert atmosphere; Milling; Under a gentle stream of argon, two zirconia-lined jars wereeach sequentially charged, in quick succession, with aliquots of5?-O-(p-toluenesulfonyl)adenosine (1b, 126 mg, 0.30 mmol or253 mg, 0.60 mmol), potassium selenocyanate (130 mg, 0.90mmol or 260 mg, 1.8 mmol; 3 equiv), anhydrous DMF (50 muL or 100 muL) and a 15mm diameter zirconia ball. The vessels were vibrated at 30 Hz for eleven hours andallowed to cool to ambient temperature. The reaction mixtures were extracted fromthe vessel in methanol (30 and 50 mL aliquots respectively). Both reaction mixtureswere combined and stirred at room temperature for 30 minutes under argon in thepresence of benzyl bromide (236 muL, 1.98 mmol, 2.2 equiv). The quenched reactionmixture was adsorbed onto silica gel and subject to column chromatography elutingwith 5?15percent (v/v) methanol in DCM. Fractions containing 3a (contaminated with a ptoluene sulphonate salt) were combined and reduced in vacuo. The tosylatecontaminated solids (104 mg) were partitioned between EtOAc (30 mL) and deionisedH2O (15 mL) followed by brine (10 mL). The combined aqueous phases were back-extracted with EtOAc (10 × 10 mL) and the organics combined, dried overNa2SO4 and filtered. The solvent was removed in vacuo to give pure product 3a as awhite amorphous solid.Yield = 65 mg (20percent).

YieldReaction ConditionsOperation in experiment
70% In acetone; for 4h;Inert atmosphere; Reflux; <strong>[40724-47-8]4-(bromomethyl)benzenesulfonamide</strong> 6 (125 mg, 0.5 mmol) was dissolved in acetone (10 mL) and then was added KSeCN (87 mg, 0.6 mmol, 1.2 eq.). The mixture was stirred at reflux for 4 h, until completion (TLC monitoring). The reaction was quenched by addition of saturated aq. NH4Cl (2 mL) and diluted with EtOAc (5 mL). The layers were separated and the aqueous layer was extracted with EtOAc (2 x 5 mL), dried over Na2SO4, filtered and concentrated under vacuum. The crude material was purified by flash chromatography (DCM/MeOH 90:10) to yield selenide 12 (70percent). 1H NMR (400 MHz, DMSO-d6) delta (ppm): 7.85 (2H, d, J = 8.39 Hz), 7.58 (2H, d, J = 8.41 Hz), 7.40 (2H, bs, NH2, exchange with D2O), 4.40 (2H, s). 13C NMR (100 MHz, DMSO?d6) delta (ppm): 144.2, 143.3, 130.2, 126.9, 105.6, 32.5. 77Se NMR (76 MHz, DMSO?d6) delta (ppm): 327.7.
