Procedure

A solution of compound 7a (3.8 g, 0.013 mol) and K2CO3 (3.5 g, 0.026 mol) in MeOH (40 mL) and water (10 mL), was stirred for 4 h. The solid was collected by filtration and the solvent evaporated in vacuo to give compound 7b (6.12 g). MS m/z (M+H+) 198.1.

Workup

  1. filtrationThe solid was collected by filtration
