N-diethyl[2-14C]acetamide (3), and the second, [hydroxymethine-14C]AJ-9677, by a two step process from (R)-3-chloro[7-14C]styrene oxide (8). When stored in the solid state both compounds undergo radiolytic decomposition in a similar manner, despite the labelled position being different, to give the dechlorinated derivative (12a, 12b). Purification of the required product was achieved after derivatization to the methyl
