Procedure
Another experiment using 3 equiv. of TBS-Cl with 1.02 g of 2,2-bis(hydroxymethyl)-6-nitro-2H-benzo[b][1,4]oxazin-3(4H)-one, gave the pure product (0.62 g, 32% yield), followed by the product with TBS-Cl (0.8 g), followed by mono-silylated material-2-(((tert-butyldimethylsilyl)oxy)methyl)-2-(hydroxymethyl)-6-nitro-2H-benzo[b][1,4]oxazin-3(4H)-one (0.56 g, 38%)
