Adding a certain compound to certain chemical reactions, such as: 99586-66-0, 2-Amino-4-chloro-6-methylpyrimidine-5-carbonitrile, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, Recommanded Product: 2-Amino-4-chloro-6-methylpyrimidine-5-carbonitrile, blongs to pyrimidines compound. Recommanded Product: 2-Amino-4-chloro-6-methylpyrimidine-5-carbonitrile

The procedure mentioned in Scheme 6 was used with (S)-methyl 6-((2-(1- ((tert-butoxycarbonyl)amino)propyl)-4-oxo-3 -phenyl-3 ,4-dihydroquinazolin-5- yl)amino)hexanoate 1.3b (110.0 mg, 0.21 mmol) and trifluoroacetic acid (480.0 mg, 4.21 mmol, 0.32 ml) in dichioromethane (2.1 ml). The resulting mixture was stirred at room temperature for 3 hours and worked-up (Method A) to form (S)-methyl 6-((2-(1- aminopropyl)-4-oxo-3 -phenyl-3 ,4-dihydroquinazolin-5-yl)amino)hexanoate 6.11. This free amine 6.11 was used with 2-amino-4-chloro-6-methylpyrimidine-5-carbonitrile (53.0 mg, 0.32 mmol) and diisopropylethylaime (81.0 mg, 0.63 mmol, 110.0 pi) in n-butanol (0.5 ml) and heated at 130 C for 2 hours. The remaining residue was purified by flash chromatography on silica gel using 0-100% EtOAc/Hexanes to afford the product methyl (5)- 6-((2-(1-((2-amino-5-cyano-6-methylpyrimidin-4-yl)amino)propyl)-4-oxo-3-phenyl-3,4- dihydroquinazolin-5-yl)amino)hexanoate 6.2q (97.0 mg, 0.174 mmol) in 83% yield. LC-MS (method 1): tR = 3.25 mi mlz (M + H)+ = 555.3.

The synthetic route of 99586-66-0 has been constantly updated, and we look forward to future research findings.
