Procedure

FmocGly/AllocGly beads were standard Fmoc deprotected with 20% piperidine in DMF leaving the Alloc glycine untouched. Then standard TBTU coupling of the photolinker (4-[(1-Fmoc-aminoethyl)-2-methoxy-5-nitrophenoxy]butanoic acid) (3 eq) to the deprotected glycine (1 eq=0.48 mmol). After coupling, the beads were washed with DMF and DCM and lyophilized.
