Paragraph 0042, (2017/04/03)
PROBLEM TO BE SOLVED: To provide a method for producing epinastine via a new intermediate which is safely synthesizable at a low cost.SOLUTION: Epinastine is produced by reacting 5H-dibenz[b, e]azepine-6,11-dihydro-6-methanamine with an N-(iminoalkoxymethyl)carbamic acid ester to synthesize an N-(9,13-dihydro-1H-dibenz[c, f]imidazo[1,5-a]azepin-3-yl)-carbamic acid ester as an intermediate and treating the intermediate with an acid (process A). As an alternative, epinastine is produced by reacting an acid salt of 5H-dibenz[b, e]azepine-6,11-dihydro-6-methanamine with an N-(iminoalkoxymethyl)carbamic acid ester to synthesize an {imino[N-(5H-dibenz[b, e]azepin-6-yl)methylamino]methyl}carbamic acid ester as an intermediate and treating the intermediate with an acid (process B).

N2-(Methoxycarbonyl)amidines 4 and analogously substituted O-(alkyl)isoureas 5 yield, on reaction with N-alkylsulfamic chlorides, sulfamides 6 and 7 which can be cyclized to give 1,2,4,6-thiatriazin-3-one 1,1-dioxides 8 or 9, respectively.Their structural assignment - with regard to the position of the acidic hydrogen - is supported by X-ray analysis of 9a.The compounds 8 and 9 show herbicidal activity.

A method for increasing the yield of rice crops involving application of an s-triazinedione such as 3-(4-chlorophenyl)-6-methoxy-s-triazine-2,4(1H,3H)-dione to the seed, seedlings, or soil in which the seed or seedlings are planted.
