Reaction Steps

To a solution of 5-(benzylthio)-6-fluoro-1H-indazole (1-2, 0.35 g, 1.35 mmol, 1.0 equiv) and tert-butyl 8-(hydroxymethyl)-3,4-dihydroisoquinoline-2(1H)-carboxylate (0.53 g, 2.03 mmol, 1.5 equiv) in THF (6.77 mL) at 0° C. was added polymer supported triphenylphosphine (0.71 g, 2.71 mmol, 2.0 equiv) followed by di-tertbutylazodicarboxylate (0.62 g, 2.71 mmol, 2.0 equiv) and the reaction mixture was stirred at 0° C. for 2.5 hours. The reaction was concentrated and purified using normal phase chromatography to yield the desired regioisomer. ESI+ MS [M+H]+ C29H30FN3O2S: 504.3 found, 504.6 required.
