1,4-oxazepan-6-ol

Conditions: temp:28.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a solution of methyl 3-chlorosulfonyl-4-(cyclopropoxy)benzoate (840.00 mg, crude, 2.89 mmol, 1.00 eq) in MeCN (10.00 mL) were added 1,4-oxazepan-6-ol (338.49 mg, 2.89 mmol, 1.00 eq) and TEA (584.88 mg, 5.78 mmol, 2.00 eq). The resulting mixture was stirred at 28° C. until the starting material was consumed. The solvent was removed and the residue was purified by chromatography (silica gel, eluting with PE:EA=3:1) to give desired compound methyl 4-(cyclopropoxy)-3-[(6-hydroxy-1,4-oxazepan-4-yl)sulfonyl]benzoate (620.00 mg, 1.67 mmol, 57.76% yield) as white solid. LCMS: 372 [M+1]. was consumed The solvent was removed the residue was purified by chromatography (silica gel, eluting with PE:EA=3:1)
