[13C2]-glycine in 15 steps and 2.5% overall yield. With the availability of [13C6]-3,5-dichloroaniline, the sulfonamide [13C6]-(2) was prepared in 12 steps and in 5.6% overall yield. For the carbon-14synthesis, a six-step synthesis gave both compounds [14C]-(1) and [14C]-(2) from the common sulfonyl chloride intermediate [14C]-(15) in 18% and 4% radiochemical yields and specific activities of 44 and 40.5 mCi/mmol
