The present invention relates to the crystalline mono mesylate monohydrate salt of N-[5-(aminosulfonyl)-4-methyl-1,3-thiazol-2-yl]-N-methyl-2-[4-(2-pyridinyl)phenyl]acetamide in a definite particle size range, particle size distribution and a specific surface area range, which has demonstrated increased long term stability and release kinetics from pharmaceutical compositions, as well as to pharmaceutical compositions containing said crystalline N-[5-(aminosulfonyl)-4-methyl-1,3-thiazol-2-yl]-N-methyl-2-[4-(2-pyridinyl)phenyl]acetamide mono mesylate monohydrate having the afore-mentioned particle size range, particle size distribution and specific surface area range. Moreover, the present invention relates to the pharmacokinetic and pharmacodynamic in vivo profiles of the resultant free base of N-[5-(aminosulfonyl)-4-methyl-1,3-thiazol-2-yl]-N-methyl-2-[4-(2-pyridinyl)phenyl]-acetamide after administration of the afore-mentioned crystalline N-[5-(aminosulfonyl)-4-methyl-1,3-thiazol-2-yl]-N-methyl-2-[4-(2-pyridinyl)phenyl]-acetamide mono mesylate monohydrate salt to a subject in need thereof.

Crystalline N-[5-(aminosulfonyl)-4-methyl-1,3-thiazol-2-yl]-N-methyl-2[4-(2-pyridinyl)phenyl]acetamide mono mesylate monohydrate having a specific particle size distribution range and a specific surface area range for use in pharmaceutical formulations

The present invention relates to the crystalline mono mesylate monohydrate salt of N-[5 -(aminosulfonyl)-4-methyl-1,3-thiazol-2-yl]-N-methyl-2-[4-(2-pyridinyl)phenyl]acetamide in a definite particle size range, particle size distribution and a specific surface area range, which has demonstrated increased long term stability and release kinetics from pharmaceutical compositions, as well as to pharmaceutical compositions containing said crystalline N-[5-(amino sulfonyl)-4-methyl-1,3-thiazol-2-yl]-N-methyl-2-[4-(2 -pyridinyl)phenyl]acetamide mono mesylate monohydrate having the afore-mentioned particle size range, particle size distribution and specific surface area range. Moreover, the present invention relates to the pharmacokinetic and pharmacodynamic in vivo profiles of the resultant free base of N-[5-(aminosulfonyl)-4-methyl-1,3-thiazol-2-yl]-N-methyl-2-[4 -(2-pyridinyl)phenyl]-acetamide after administration of the afore-mentioned crystalline N-[5-(aminosulfonyl)-4-methyl-1,3-thiazol-2-yl]-N-methyl-2-[4-(2-pyridinyl)phenyl]-acetamide mono mesylate monohydrate salt to a subject in need thereof.

Crystalline N-[5-(aminosulfonyl)-4-methyl-1,3-thiazol-2-yl]-N-methyl-2-[4-(2-pyridinyl)phenyl]acetamide mono mesylate monohydrate having a specific particle size distribution range and a specific surface area range for use in pharmaceutical formulations

The present invention relates to an improved and shortened synthesis of N-[5-(aminosulfonyl)-4-methyl-1,3-thiazol-2-yl]-N-methyl-2-[4-(2-pyridinyl)phenyl]acet-amide and the mesylate monohydrate salt thereof by using boronic acid derivatives or borolane reagents while avoiding toxic organic tin compounds and to the mesylate monohydrate salt of N-[5-(aminosulfonyl)-4-methyl-1,3-thiazol-2-yl]-N-methyl-2-[4-(2-pyridinyl)phenyl]acet-amide which has demonstrated increased long term stability and release kinetics from pharmaceutical compositions.

N-[5-(Aminosulfony1)-4-methyl-1,3-thiazol-2-yl]-N-methyl-2-[4-(2-pyridinyl)phenyl]acetamide mesylate monohydrate
