Procedure

To a solution of 10-tert-butyl 4-ethyl 5-methyl-13-oxa-3,6,10-triazatricyclo[7.4.0.0{2,6}]trideca-1(9),2,4,7-tetraene-4,10-dicarboxylate (757 mg, 2.09 mmol) in 50 mL of THF was added LAH (2.364 g, 6.27 mmol) at 0° C. The mixture was stirred for 3 h at room temperature. To the mixture was added sodium sulfate decahydrate (257 mg) and the mixture was stirred for 15 min at room temperature. The solid was removed by filtration and the filtrate was concentrated. The residue was purified by reverse phase column chromatography (eluting with 15% acetonitrile in water, with 0.1% NF3—H2O) to give tert-butyl 4-(hydroxymethyl)-5-methyl-13-oxa-3,6,10-triazatricyclo[7.4.0.0{2,6}]trideca-1(9),2,4,7-tetraene-10-carboxylate (630 mg, 94% yield) as a white solid. ESI MS: m/z 320 [M+H]+.
