YieldReaction ConditionsOperation in experiment
93% With triethylamine; In dichloromethane; at 20℃; To a round-bottom flask equipped with a stir bar was added 17a-b (1.0 eq), Boc2O (1.1 eq), CH2Cl2 (10mL/mmol), and triethylamine (1.5 eq). The reaction mixture was stirred at room temperature overnight. The reaction was concentrated in vacuo and partitioned between ethyl ether and 1M HCl. The organic layer were separated, washed with saturated NaHCO3 and brine, dried over MgSO4, and concentrated in vacuo to give a white crystalline solid. 4.2.4.2 128 tert-Butyl (4-cyanobenzyl)carbamate (18a) Yield: 93%.

93% With triethylamine; In dichloromethane; at 20℃; General procedure: To a round-bottom flask equipped with a stir bar was added 27a-b (1.0 eq), Boc2O (1.1 eq), CH2Cl2 (10 mL/mmol), and triethylamine (1.5 eq). The reaction mixture was stirred at room temperature overnight. The reaction was concentrated in vacuo and partitioned between ethyl ether and 1 M HCl. The organic layer were separated, washed with saturated NaHCO3, brine, dried over MgSO4, and concentrated in vacuo to give a white crystalline solid. Example 86 Synthesis of 210 tert-Butyl (4-cyanobenzyl) carbamate (28a) (0243) The synthesis follows the general procedure described in Example 85. Yield: 93%.

YieldReaction ConditionsOperation in experiment
48% In N,N-dimethyl-formamide; at 60℃; Example 5; Step A; 4-Cyanolbenzylamine (1.1 g, 8.33 mmol), 4,6-pyrimidine dicarboxylic acid methyl ester (1.77 g, 8.33 mmol) were dissolved in N,N-dimethylformamide (20 mL). The reaction was stirred 60 C. overnight and concentrated. The brown solid was purification with ethyl acetate and hexane (gradient) to give product as light brown solid (1.18 g, 48% yield).

YieldReaction ConditionsOperation in experiment
With 4-methyl-morpholine; In hexane; water; ethyl acetate; N,N-dimethyl-formamide; a Boc-D-Phenylalanylproline (p-cyanobenzyl)amide 2.0 g (14.6 mmol) of isobutyl chloroformate were added in 2 min to a solution of 5.1 g (14.2 mmol) of <strong>[38675-10-4]Boc-D-Phe-Pro-OH</strong> and 1.53 g (15.2 mmol) of N-methylmorpholine in 15 ml of DMF at -15 C., the mixture was stirred for 10 min and then a solution of 1.9 g (14.2 mmol) of p-cyanobenzylamine (W. Walter et al., Ann. 660, 1962, 60) and 1.53 g of N-methylmorpholine in 3 ml of DMF was added. After stirring at -15 C. for 3 h, a TLC check (CH2 Cl2 /MeOH, 9/1) showed no detectable starting compounds. For isolation, the reaction mixture was poured into 200 ml of water, when an oil separated out and, after a short time, solidifed and was broken up and filtered off with suction. The still moist residue was dissolved in a mixture of 250 ml of ethyl acetate and 50 ml of ether and washed successively with a 5% strength aqueous citric acid, bicarbonate and saturated sodium chloride solutions. After drying over Na2 SO4, the solvent was removed by distillation under reduced pressure, and the residue was mixed with n-hexane and then filtered off with suction. Recrystallization from 50 ml of ethyl acetate afforded 5.6 g of TLC-pure product, m.p. 156-157 C.
