Participants

Reaction Steps

A solution of 3-[4-(3-amino-propoxy)-3,5-dimethyl-phenyl]-1-((1aS,5aR)-1,1,2-trimethyl-1,1a,5,5a-tetrahydro-3-thia-cyclopropa[a]pentalen-4-yl)-propan-1-one (18 mg, 0.043 mmol, Example 81) in DCM (2 mL) is treated with DIPEA (22 mg, 0.171 mmol), TBTU (19 mg, 0.06 mmol) and glycolic acid (5 mg, 0.064 mmol). The mixture is stirred at rt for 1.5 h before it is separated by chromatography on prep. TLC plates with DCM:methanol 9:1 to give N-(3-{2,6-dimethyl-4-[3-oxo-3-((1aS,5aR)-1,1,2-trimethyl-1,1a,5,5a-tetrahydro-3-thia-cyclopropa[a]pentalen-4-yl)-propyl]-phenoxy}-propyl)-2-hydroxy-acetamide (7 mg) as a white solid; LC-MS: tR=1.01 min, [M+1]+=470.07.
