摘要:
A highly stable crystal of (1S)-1,5-anhydro-1-[5-(4-{(1E)-4-[(1-{[2-(dimethylamino)ethyl]amino}-2-methyl-1-oxopropan-2-yl)amino]-3,3-dimethyl-4-oxobut-1-en-1-yl}benzyl)-2-methoxy-4-(propan-2-yl)phenyl]-D-glucitol, and a process for producing the crystal are provided. Specifically, an ethanolate having the following physical properties, and a plurality of other crystal forms transformed from the ethanolate are provided: (a) Having peaks at 2θ=5.9 degrees, 17.1 degrees, 17.6 degrees and 21.5 degrees in X-ray powder diffraction (Cu—Kα); (b) Showing characteristic absorption bands at 3538 cm−1, 3357 cm−1, 2964 cm−1, 1673 cm−1, 1634 cm−1 and 1505 cm−1 in an infrared absorption spectrum; and (c) Having a melting point in a vicinity of 111° C.
摘要:
Disclosed is a process for efficiently producing a compound represented by formula (I): wherein R1 represents aryl, amino, alkyl, or alkoxy; R2 represents a protective group of the carboxylic acid; and R3 represents an alkali metal, a hydrogen atom, alkyl, aryl, alkylsulfonyl, arylsulfonyl, or trialkylsilyl. This process is characterized by reacting a compound of formula (II) with a compound of formula (III) in the presence of a transition metal compound.
