DABCO-catalysed cyanation of 6: solvent studies.^a

entry	solvent(s)	conversion of 6b	ratio 13:14:15c	yield 13d
1	DMSO/H2O 1:1	100%	100:0:0	90%
2	EtOH	100%	17:32:51	ND
3	MeCN/H2O 10:1	100%	100:0:0	75%

^aReactions were performed using 200 mg 6 in 20 mL solvent. ^bConversion of 6 was determined by LC–ESIMS. ^cIdentities of 13–15 in the reaction mixtures were confirmed by ¹H NMR and LC–MS and product ratios were determined by ¹H NMR after work-up. ^dYields were determined after purification; ND = not determined.
