Procedure

Methanesulfonic acid 3-methanesulfonyloxymethyl-1,3-dihydro-isobenzofuran-1-ylmethyl ester (12.1 g, 36 mmol) and conc. NH4OH (50 mL) was dissolved in acetonitrile (100 mL) and heated at 100° C. in a sealed vessel for 2 h. The reaction was then cooled, adjusted to pH 5-6 with 1 N HCl and extracted with diethyl ether (100 mL). The aqueous layer was then basified with 10 N NaOH and extracted with diethyl ether (2×100 mL). The later organic layer was dried over MgSO4, filtered, concentrated and purified with silica gel chromatography (0-15% MeOH in CH2Cl2) to obtain 12-Oxa-10-aza-tricyclo[6.3.1.0*2,7*]dodeca-2,4,6-triene as a brown, viscous oil (5.1 g, 88%). MS (m/e) 162 (M+1); HPLC (93%)
