it into RNA. However, the GNHMe phosphoramidite posed a significantly greater challenge due to lack of a suitable −2′-NHMe protecting group. After testing several strategies, we established that allyloxycarbonyl (Alloc) provided suitable protection for 2′-N-methylamino group during the phosphoramidite synthesis and the subsequent RNAsynthesis. This work enables AMC analysis of guanosine’s 2′-hydroxyl
