Procedure

A mixture of 4-N-(t-butyloxycarbonyl)-1,1-dioxo-2,3,4,5,6,7-hexahydro-1,4-thiazepin-6-one (8.39 g, 31.9 mmole) from Example 6, 2,3-dichlorobenzaldehyde (5.58 g, 31.9 mmole) and 2-(N-benzyl-N-methylamino)ethyl 3-aminocrotonate (7.91 31.9 mmole) were heated to reflux in 40 mL of ethanol for 17 hours. The reaction was cooled to room temperature, filtered, and the solid washed with 50 mL of ether to obtain the title compound (10.72 g, 50% yield) D.C.I.M.S. (M+H) 668.
