The reaction of 2‐bromoethylamine 1 with methylisothiocyanate 2 under mild condition gave 2‐methyl‐amino‐2‐thiazoline 3 as the major product together with two kinds of byproducts, 3‐( N ‐methylthiocar‐bamoyl)‐2‐methyliminothiazolidine 4 and N,N ′‐dimethyl‐ N ‐(2‐thiazolin‐2‐yl)thiourea 5. Thermal isomer‐ization of 5 to 4 was observed. The structures of the byproducts were confirmed by X‐ray crystallography.
