Procedure

Piperidine (3.19 ml) is added to a solution of 3-(3-chloropropoxy)-1-hydroxymethylbenzocyclobutene mesylate (2.45 g) in toluene (32 ml) and the reaction mixture refluxed under nitrogen for about 12 hours. The reaction mixture is diluted with ethyl acetate and extracted with saturated NaHCO3 followed by saturated NaCl. The organic extract is dried, filtered and concentrated yielding the crude product used in the next step.
